While I have a difficult time imagining much "snap" out of trying to spin up that monster flywheel *grin* I see what your saying. Couldn't you build a rod for the accel pump that uses some turnbuckles and threaded rod? Maybe allow you to shorten or lengthen it as needed?

Surprisingly it's pretty snappy, and getting better with tuning. I was surprised. If your on gravel, dirt, or sand you can pitch the rear end around pretty easy. 3000lbs and about 2-3 times the power of the stock (L134 4cyl) engine is pretty fun. I can't wait till I build the spare motor a little bit...another 100hp would be fun!

The link rod is a really funky shape that would be hard to duplicate AND provide some way for adjustment. All in all the stock link rod works with slight 'adjustement' for the two outer pump arm positions and at least 3 positions on the lever arm. If you needed to use the inner most positions on either arm I think you would have to make a new arm.

It would be really cool to find an all aluminum Buick V6 or the Rover/Buick aluminum V8 to shave even more weight and add some ponies...
Zooooooooooooooooooooooooooooooom!

700hp....that is practical right? All aluminum twin turbo buick V6 from TA performance.....

In reality I think going to an aluminum intake will be a nice 1st step. The 'spare' engine is probably going to get a 4bbl intake and 4100 motorcraft carb. I have been looking into retrofitting the better flowing even fire heads on my odd fire block. That would open up the intake choices a bit too....

[jeepdreamer]

Oh... SURE! That is most defiantly practical! Kinda like the 500 Caddy I put in my old Galaxy Station wagon.
I'm not sure but I kinda remember there being some reason why the heads from an "even" won't work on an "odd"...But I may just be remembering stuff related to exhaust manifolds or maybe Dizzys.? I do like TAs valve covers a lot though.

[Metcalf]

Supposedly there is a way to slightly mod the water passages to get even fire heads to work on an odd fire block.

I wouldn't mind finding a 4.1 donor motor also....Then make it an odd fire just to make people scratch there heads....

I guess I have to ask why the "like" for odd fires? I had a beater POS 79 toyota truck that had a odd-fire/th350 swapped in (poorly I might add), but I was not that impressed with it as a motor. Seemed difficult to tune based on the fact that no matter what I tried, it wouldn't smooth out, so it was hard to tell if I was going in the right direction or not. I realize mine was not a good example, but based on the realitively limited support compared to the even-fired motors, I don't see the allure. By the way, the truck came with a 4.1 in the bed, the PO was planning on swapping it in and I sold the truck before I got that far.

Don't get me wrong, I love what you are doing and am really impressed with what you have accomplished, I just don't see what the odd-fire has going for it other than the nostaglia.

The odd-fire CAN be a really great engine. Like all retro stuff these days you just have to dig a little deeper for information, parts, etc.

The 225 had a 50lb flywheel in manual applications. This makes for GREAT ultra low end stall resistance. I have seen my engine bounce the tach off zero and come back. The 225's also came with a 9.0:1 factory compression ratio. A lot of the later even fire engines where down a few points in compression compared to the odd fire engines.

The willys had one when I bought it also....so.....I used what I had. I have had really good luck with it in general. I had the chance to pick up a complete running spare engine for $250 so I did.

Most of the later 3.8 and 4.1 engines where pretty much dogs compared to the 225 because of the emmissions, smog, and the lower compression ratios. The later motors did probably have more potential with the 4bbl intakes and better heads in the long run.

The 225 is no slouch however, it just needs a little more love in a few areas....

[locrwln]

Gotcha and I get the "since it was in there". That was the one thing the 4.1 had going for it, 4bbl intake. But yeah, they need a lot of work to make some power, but guess if you are willing to spend the time/money, they can be little screamers.

[Metcalf]

Yup, I think you would spend just about the same on either motor to make the same power. At some point the even fire engine will probably be able to make more power. At that point though your probably talking race gas however....

If I can get 225hp out of my little 225 I will be way happy That doesn't look to be THAT impossible on pump gas with a good all around power band. Honestly, my 225 is mostly lacking in the 3000-5000 range right now. I would give up a little low end power for more mid and top end. I can lug it around in 3rd gear with 4.30 gears and 35" tires at like 1200rpm pretty easy....
