I just gained several IQ points watching this. One very interesting detail is need to hold back on unshrouding the exhaust valve on the short side radius to not overwhelm the poorly flowing side of the port. This is where DV's extensive expertise shows. More is not always better.

Bo-port is in Carson City, NV. Bo has ported a bunch of these heads, has a stellar reputation in the Lima community, and stands by his work.

I’m in sparks man sweet🤙🏼

😮 I had no idea! First with the 2.3 Lima, then suddenly (and FINALLY) I can actually visualize what de-shrouding does and looks like effectively. Thank you for helping me to finally see it in my head what is going on when folks talk about de-shrouding. Maybe I should have said "ViZualize" ha! Thanks again Mr. Vizard, another great video. Edit - my god those are gorgeous looking chambers after you polished them. You can literally see the time, effort, & expertise

I understand the majority of Ford Rangers came with the 2.3. I am expecting to turbo my Ranger for loads O fun... Thanks David

David could get massive power out of a lawn mower !!! Thank you for all the voodoo that no one else will show you

Excellent video David I liked seeing more of the roughing and process of porting. Eagerly awaiting a poly quad video on your eco boost mustang

Looks like a re-upload? Here's a like and a comment to help with the algorithm.

Added to a patinaed 72 pinto ultimate sleeper. That car weighs like 1900 lb. Fun!!!!!!!

Brings back memory of DV's ford 2.0 engine tuning book❤!! They both have heads with that charm of having inclined (as opposed to pushrod heads) and shifted valves (as opposed to hemi chamber overhead cam heads). Love them

Thank you so much for all your time putting these videos together!

Oh No!!! MY motor!! edit: I have an Esslinger aluminum D-port lima head if you ever wanted to "experiment" with it out of curiosity... I just need it back when done (and it needs to work still) 😁 Been a fan for a while! Thanks for this video especially!

Thanks for sharing, all the best to you and your loved ones

Thank you David very interesting and informal

Awesome to see all the chamber work and to here the whys. I mainly do diesel heads so no chambers to deal with.

Another excellent article

Yes, I see the advantage, thank you sir

Good job DV!

Wonderfull episode. Special because i still have this engine 2850CC one from Esslinger with all the go fast parts, also with SVO aluminium head Maybe another episode of headwork on a N/A driven engine

David I can only imagine what would happen if you tuned a brand new 2024 Harley-Davidson Low Rider S or ST. That new M8 engine would benefit from your experience and skills.

George Bryce is a wealth of knowledge on bikes.

I ran the 2300 engine naturally aspirated in a pinto back in 1979 it was a good running car , i went to atco raceway with it and came home with the trophy just two of the cars i beat that day had big blocks in them a 440 roadrunner and a 55 chevy with open headers against my little 4 cylinder street car everyone thought I had a v8 in this car , they are a great little motor you just have to know what to do with them, I still keep all my tricks to myself with this one to this day

Thanks DV! v/r wh

Always felt Ford US hated small cars. Start with the Cortina GT 1600cc Kent take it to 2000cc SOHC and ... less horsepower. Then with an example of a fair rally and autocross car deliver the Pinto. Seemed like the low performance and bad weight distribution with extra understeer built in was on the showroom to test drive and sell you a Mustang. What they considered their small starter car since you really should be driving off the lot in a LTD or a Lincoln Town Car. Always wondered... if the front axle was a bit more forward, the engine back just an inch, closer to corect geometry on suspension, and at least a portion of what the increased displacement should have delivered in horsepower. There would have been fewer Toyotas and Datsuns imported. Yes, probably fewer Mustangs sold, but many people wanted a smaller starter car so they either bought the Pinto anyway or just walked off the lot without buying the Mustang.

3:54 My nephew put a 67mm turbo on a 2.3 it made quite a bit of power. He was going to use the Volvo head

The Lima is interesting. It's built very, how should I say, agriculturally. It's more or less too dumb to die under most circumstances, and getting 1000hp out of one represents more than 10x what it would've ever made from factory. I think the later 2.5L variants eventually cracked the 100hp barrier /just/.

I thought the 2.3L Lima had 2 spark plugs per cylinder. I had a 2.3L in a 1993 Ranger and it had 2 plugs per cylinder and I always thought that was Lima motor.

David on the transition of the semi plateau on exhaust i kinow you said the depth was going to be an issue is it because the plain leading up to the valve must be done within your scribed area i have your books and should do my home work and usually dont see much more than chinia v8 knockoffs which make an easy transition i will appreciate your or adams input ty

Howdy Mr. Vizard! Please correct the link in the video description. The link is missing "Day" as in 14_Day_Trial. 🙂

Would you do the inner ports first to get the flow and swirl numbers and only improve the outer to match?

Still a 404 error, the correct link needs to have "Day_" added after the "14_" It needs to be "Flow_IOP_14_Day_Trial" 👈🏿

One question David, does the software also work for a cylinder head with 4 valves per cylinder? Regards Gregorio

Yes, it does. I believe it will also do 5 valve heads.

@danyan7

for 4 valves, he recomends, polyquad. good flow, and a lot better turbulent air makes better combustion and power

HAve you worked with EFI.

David, have you ever seen Jim Fueling's BBC heads? Tiny valves and figure 8 chamber. What are your impressions? Are they real or a scam?

I tried your link, doesn't seem to work.

These engines have been used for decades already in 4 cyl dirt track cars. It's a stalwart that has been modified for race use since the day it was introduced for goodness sakes.

VP race fuel.

that quote 16, 4 Hp per Cubic Inch... One Cubic Inch would be 16,387 CC. And then 16,4 HP out of it? I either cannot calculate, or this is a mistake. 🤔

the motor (stock anyway) is 140 cubic inches / 2300cc edit: oh I see what you mean... I don't quite know what he was talking about with that... lol

Have you ever considered having one of your Lima heads with all your proprietary combustion chamber and intake/exhaust port work…fully scanned by a computer ?and be able to CNC the same shape to every head sent to you…save you some work and will provide the next generation of Lima tuners …a legacy of your Art

To bad I wrecked my old Pinto . Had to put her down.😢
