Try starting with some small engines, being they are smaller it's easier and quicker to see results and test theories. I did a little mix/match of connecting rods and wrist pins between early and late models on a Briggs 49 cubic inch v twin and saved like 30 grams per hole from using the early rod and pin. I happened to have both types of engines apart for other reasons and noticed one of them had a much thinner wall on the wrist pins. So I weighed the rods and found more weight reduction. She picks up nicely now and carries it to 44-4500 or so , especially with some port work on the heads. Go ahead ,shave like .150 off a head and see what it does. I'm just saying it's easier and faster to try on a small engine and then transfer the idea to an automotive engine.

this is old school horse power secret gold! I wish more people would share these tricks

The videos with just David are SOO much better, I could listen to this man all day

This makes the rod look gorgeous, reduces the weight and stress concentration.

All these small things I've never even thought about all add up to making an engine run more efficient, which means more power to the wheels, instead of losing power to the inefficiencies in the engine.

I have a 87 318, I am saving every post, with the plan to implement all you have taught me. Thanks for your lessons.

Same! With all this 318 tech gold on hand from DV, ANDY, UTG, & Charles Servedio- we are definitely going to pick up some horses ...that's for sure!

This collaboration with the people involved is literally horsepower GOLD!

Being brittish your books tuning my crossflow cortinas and anglias were legendary. Dave mate you and Geoff howe were and will always be my idols.

By the way, raising money for St. Jude’s is great thing! Thank you! I’ll make sure to like every video I see. That said, the quality and quantity of subjects you show us is priceless in my book! I hope the young guys watching this are using these tips to build their own killer projects! And maybe, through some miracle, I’ll be able to build my own project.

WOW I had never once considered the airflow in and out of the bottoms of the cylinders!!! Now I have to look at the whole engine as an air pump, not just the part of the cylinder above the piston!!!

You have a style of presentation that reminds makes listening and learning relaxing! 👍

I always wondered what was being done to oem rods in an old-school build. Thanks, keep it coming please.

i remember back in 1973 doing this to a 186 ci holden 6cyl - in the back shed block deburring and oil gallery blending and we actually polished the rod beam on a big wheel to mirror finish all 6 rods and push rods .

Prior Video i guessed 23.4g off the little end. Im going to guess another 21g off the beam for a total reduction of 44.4g. Great stuff DV

ah 49 grams per rod reduction I've always been a believer in crank case porting for reduced pumping loss but i always thought more about it getting from one cylinder to the next past the mains i cant believe i overlooked that obvious sharp edge thanks David

The old “Chevy Power” manual, back in the late -70’s / early -80’s, had a good illustration on reworking big block rod forgings for small block applications, that went into great detail, similar to what DV is doing here.

Thank you for your time

Thank you! I look forward to applying this on my next 318 build.

I can't wait to see this engine finished.

57 grams total. The rods are a work of art and performance!

How to Modify Ford S.O.H.C. Engines Book sitting on my bookshelf having been moved to 10 different houses and now to a different country, great to see you David still doing your thing.

I’ll SWAG that weight at 15 grams. It certainly enough to throw the engine out of balance! Back when I worked at an Auto Parts and Machine store, we had a customer that collected Corvettes. He was a pilot who flew the Hawaii route, and had almost every year vette in his collection. He bought a new Vette in 81, broke it in and then took it to Firebird/Wild Horse Pass raceway to see what it would do. A rod let go in a big way. Then he brought it to us to repair. There was no repair to be made. Inside the oil pan we found a whole lot of gravel, and a few hunks of identifiable connecting rod. Between rod to rod of what was left we found a variance of 5 grams. There was no way to tell how much the exploded rod weighed. We ended up building him an old school 350 with 461 straight angle heads.

I am guessing 51 grams per rod for the total modifications. Very cool attention to detail. Each 1 HP gained is taking time and knowledge to attain. It all adds up.

Pure Gold David.. thanks so much for doing these vids. Can you please do a session on the oil pan, I’ve heard crank scrapers help power remove oil from wind ages etc. Would be great to get your teaching on it..

I'm saying a 51g reduction in weight.. This is AWESOME!! Gonna start working on my connecting rods. LOL

Got to admit at approx 13:20 that really wasn't something a thought about it... really good advice! totally agree about notches seen a many hundred-kilo spinning casting broken into a half-machined right angle and solved from fatigue cracking by a deliberate "U" groove actually cut into casting reducing the section however totally solving the issue...the same method and concept! Good stuff thanks, Jm

Great viedeo, can't await to lighten and reduce stress with the polishing job on all my further engine builds.

Really enjoying this sir. Followed you in books and print since the 70s and my mini days. Your books taught me to port cylinder heads and I had great enjoyment and success from that. That and my die grinders and arsenal of grinding stones and cutters have stood me in great stead for many other of life's automotive challenges. Keep up the great work. It inspires us.

Sir thank you for what you’re doing I’m an old Mopar guy for many years and I just learned a little trick about chamfering the bottom of the cylinder walls that is really neat anyway to thank you for helping the children at Saint Jude‘s I’m sure I’m not as old as you I’ll be 67 in February but I remember Danny Thomas he was a good man and thank uncle Tony to he’s a cool dude this is six in a row jim from Kennerdell Pennsylvania I go by six and row jim I have a 1991.5 dodge pick up and when the engine sits here and runs it has some clattering going on I’ll give you three guesses what’s going on under the hood it’s got a six banger when was last time you heard that again thank you for helping Saint Jude❤❤❤❤❤😊🎉

I just love this project.

Mr. DV you have given me confidence to try to work on my 1st motor! Your videos are Top Rank go-tos to me! I think around 7 grams each has been lightened from rods.

I'm loving this build👍

2.7 ounces... I'm a little late but I just found yur channel I'm a mopar guy so I guess uncle Tony's algorithm put me on to u and I'm very glade for that lol I'm a new engine builder and I need all the help and info I can get

Thank you David for this detailed string of videos, a lot of what I will use on my 365cu LA 360. My guess on weight reduction of head portion of rod only is 36 grams. Thanks again

Nice work on the stress relief, I’d guess 16-18g off the little end and 30g total including the improvement big end around the bolts

You have so much experience and knowledge how great is that thank you always ❤ learning happy new year

I'm going to say that if got your crew on it it will get more free HP. Every little bit will eventually add up and more is always better than zero because you are skeptical or slacking, and possibly can't get your hands on the tools. If is the last because of budget or just don't know anyone who has the stuff you need, is a different story than the first two. Something that costs nothing if you are able to get this done is a great tip. I'm glad that Unity Motorsports turned me on to DV. Happy Holidays and I hope that you had a Merry Christmas and I will wish you a great and good New Years!

cousin of mine got our grandfather 78 Dart with a 318. he put 4bl carb, headers and a mild cam, clean the heads up and put new valves and gids in. i was shocked what lil he done made that big of a change in that 318.

Total mass removal has to be close to 120 grams per rod. Good old school hot rod stuff

Awesome episode. Keep it up!

I'd assume 25g worth of metal cut out of each rod. I'm excited to see more details about this project!

Great content. I really appreciate the knowledge. The rods I say were reduced by 2.5 grams

Freakin awesome! Thanks for showing that David.

I’m guessing a 19g reduction DV. Always great videos! 🏁

Looking forward for these episodes

Super cool stuff 😎thanks David

I'm thinking 38.8 grams per rod. Thanks for sharing all your knowledge Dave.

3 times out of 10 you're a knurled bolt shank, you don't hear us complaining! Oh and 52 grams lighter!

If you got real generous you could do a winner for each stage of rod lightening/polishing 😁. I haven't made a guess yet but that 'lump' on small end has to be relatively heavy. Very interested in the cylinder base mod, I've often wondered about airflow around that edge but never actually tried any mods there as motorcycles usually have a bevel because piston goes in from bottom (until 'uni-block' started to be common in 80's)

@modelnutty6503

Жыл бұрын

radius to the bottoms is something I'd never thought about, but makes sense. not just the air flow but the extra oil it'd throw into the skirt area too for reducing friction+wear would help free up some power.

Great video. My guess is about 37 grams of material removed per rod. Looking forward to the next video. :)

It's a wild guess but 65 grams total reduction. Great video. Following this build. I expect a lot taken from the big end later too

Thanks again D.V. 90 grams per rod is my guess, taker easy, and happy new year bud.

This was awesome

The REAL DEAL !!

I did this mod on my rods. Nasty business with all tha small iron slivers. They followed me into the house and I think I had to pull them from my feet for a few months after 😅 I also removed the pad on the big end so I saved quite a bit even on my v6.

Hi David; another great video! I'm going to guess a reduction in weight of 23.7 grams per rod; well that's what I managed to achieve lol! Although you probably beat that

great video thank you david

I think that you lightened the rod by 26 grams. Thanks, David for another informative vid. Paul.

Great series Mr. Vizard! With respect to your block mod, I would like your thoughts on running a vacuum pump to create a negative pressure in the crankcase. Thank you.

Thank you !

Great info D.V. My guess is 16.5g on that modification.

I love your videos

You could save a lot of work if you could locate a set of poly rods. They are already set up for full floating pins and are much lighter. Use in the 273 & early 318 engines with forged steel cranks. Some balancing required.

72 grams is my guess since it's my lucky number or favorite number haven't figured that out for sure yet🤣

Thanks !

23 grams removed. Thank you Mr. Vizard for all you do. You are a special person. Any way you could do a video on golf ball dimpling of a combustion chamber and/or intake runner? Some diesel guys swear by it, just wondering your thoughts. Take care

More like ounces! Lets say 66grams! I was talking about the total process! After you finished!

I'm guessing 32 grams .. Keep em coming DV!

DV I LOVE 💕 YOU!

I’m gonna guess a moderate 43 grams total weight reduction. Love the technique’s!

My guess is 52 grams total was removed from the rod. Great video!

I wrote 4.5 ounce or 126 grams per rods last night but cant seem to find it going through the comments. Thanks for the content.

Very time consuming but free horse power with polishing the rods reducing the weight of those heavy chunks of steel connecting rods. Yes to also blending the cylinder bores as anything to improve the pumping loss to friction of the air oil turbulence inside the engine. David will you blending the sharp edges of the counter weights or go full on knife edging the crankshaft? I myself would do a combination of both. I still see the carburetor will still be the biggest hurtle to overcome. As the cylinder head air flow will be top notch and the reduction of parasitic drag from the oil in the pan will make this engine make great runner and net the goal of 318+ horsepower easy if the fuel is there.

Thanks
