Could you imagine? Going out your back door to your shop to grind custom cams every day? Sounds pretty far up the list of dream jobs I have 😮

If you need a cam core to regrind for your 318 project, I have several 340 nhra stock class cams with tighter lc you can have

I hope this happens! I want to see what these guys can do! I want to see how much power a cam can make for the motor it was made for instead of a cam company what they want it to be. I’m so hoping to see this I can’t imagine how much more power it could make.

Great video as always David. Always good to see you.

Here in the Northwest we have Delta Cams that do regrinds and lifter dressing.

I Got My Custom Camshaft Last Week From Comp Cams. Luckily They Had Cam Cores In Stock For My 3800 V6 97+ Engine. I Originally Speced A Cam For 108 LSA Based On The Trends Of A SBC And You Quick 128 Formula. Unfortunately They Said The Tightest LSA They Could Grind Was 110LSA. So I Went Back To Drwaling Board And Speced A 110LSA Cam. Either Way It Should Be Much Better Fit For How I Use My Engine Than My 117° LSA Cam I Had In It.

Jacque would have loved the Long Hood Peterbilt’s too. With the six car enclosed double deck trailer. Hauling her nice cars to races and car shows. She’ll be back someday King David. She’ll be back

Thanks for the update!

Can't wait for the LS3 Enforcer info. Considering them for my 3/4Tn truck. They seem to be a better fit than the stock LS3's. Them heads, an mild 270/270 (seat to seat) @ 109+4 cam, and proper tuning should give me plenty of smiles-per-hour. This truck is my daily, plus hauls a dirt car and tractors on the weekend.

Last year, 2023, I had a cam spec'd by Jones Camshafts. My SBC retro-fit cores were in stock (hydraulic rollers and distributor gear as well) and start to finish, (payment submitted to delivery on my Canadian doorstep) was inside of six weeks. Not bad by my estimation. Also very competitively priced. You've spoken highly of Mike and between that and his presence on Speed-Talk, he was my vendor of choice. Interesting story too about his spec, revision 2, and what Torque Master cranked out.

@ David Vizard: A bigger down pipe with a bigger cat. Yes! I said so to a friend but he didn't believe me. The down pipe and the bigger cat. After the cat, so far as my thoughts go, could the mid pipe be of a smaller size. But bigger then factory. Also, after the cat you can mount a conical piece of tube to let the pulses flow into the some what smaller diameter. - What are your thoughts on this? My own set is a spaghetti manifold and a sport cat. On both sides of the cat. the diameter is the same (sport exhaust system). The tubes of the spaghetti itself are lots smaller an flow from 4 to 2 to 1.

I never miss you Andy , and uncle Tony 😊

I have my truck apart. I really wish I could buy a mild cam, as long as I have things apart. The only way that's happening after this dry spell is if someone mis-ordered and had to get another cam for their needs.

Very interesting as usual thank you

Thank you David for the info.. As always, great video!👍

King David Sir. Elvin has been doing research:) Edlebrock Torker 2 Camshaft.. 108 degree LSA 480 lift, just short of your .250 formula:) But - with 1.6 - 1.7 rockers You’ll achieve your .250 rule We know the Torker 2 intake needs to be ignored, but whoever designed the cam, must have been one of your loyalists, knights behind the curtain.

"Decreasing the back-pressure on the exhaust stroke" in order to gain some HP. Interesting idea.

🔔😎 Can you please do a video about pushrod length and valve train geometry. And noting the roller rocker tip to valve stem offset that increases low lift opening. Pushrod 5.0 Ford mild modified, here. Thinking 1.7 PRW Sportsman on a stock 5.0 cam with ported 289 heads. Thank you !!

Sir i have been binge watching your videos and I am understand some of your videos are describing but I have a question how does on get the cam back in the correct lsa if it doesn't add up using the degree wheel i hope i am asking this question correctly.

If LSA isn't perfect have the cam reground. If you want to advance or retard cam timing use an aftermarket cam and crank gear or offset key-way.

@@Twogreenfeet I just re read my comment and the auto correct spelling is leaving out some of the correct spelling ok if the cam that someone buys is not adding up using the degree wheel so one has to use the cam or crankshaft gears that has a Straight up zero or advanced or retarted key way to get the cam in the correct lsa as needed? I have researched different cam timing chain choices and there's some that have that 0 degree and 4 degree advanced or 4 degree retarted or multiple timing choices to get the camshaft in correct timing if it's not correct in using a degree wheel I apologize if what I am describing is not explained correctly I'm getting into building a engine correctly at my age now in my 50's and want to understand everything about building engines it's always been a bucket list of to do and understand everything about building a engine correctly and optimum the most power out of them .
