Re: Engine Masters Challenge early hemi

congrats, those are bodacious HP/torque numbers it would be really interesting to see what a low-buck 331/354/392 type engine using stock parts would do, i.e. "555" heads, cast iron intake/exhaust manifolds, 4bbl Holley, and maybe a modern solid flat tappet cam, and 9.25 CR. For how popula...

Re: realistic hemi question-what to put it in ?

here is some of the procedure for early Hemi to "B" and "E" body. It's self explanatory- question: why not just bolt in a 440 or 426 ? There's no incentive to go through all this, IMHO. But you can make the judgement call for yourself. http://www.moparts.org/Tech/tech/pages/early...

Re: realistic hemi question-what to put it in ?

I say this with all due respect, not trying to flame anyone, but why would you put an early Hemi in a Cuda in the first place- when a 440RB/426Hemi will bolt right in and make more power ? The early Hemi in Cuda swap just makes no sense to me- unless the engine, parts, and labor was free, and I had ...

the ports on those early Dodge hemi heads are very small, 100 cc intake ports. The 1956-57 polysphere Dodge heads actually have bigger ports 125 cc's.

Re: Can this block be saved?

While treasure hunting for early Hemi parts I came across a 392 block (casting # 1673729-5) setting in the dirt behind a shop, the block is basically a short block, no heads or intake, and it appears the block was setting outside for a few years, the lifter valleys were full of dirt and the piston ...

D63-1 would me a 270 Poly -- but if you look at the pad, it looks like D63-I. From the photos (see below) you can see that it's definitely got Hemi heads. Is it...

thanks fellas

what's your opinions about a Hemi in a 1949-54 Chevy 2-door ?

or late 1940's Studebaker ?

I ask this because there's a few buildable bodies of such around for sale. The Stude is kind of stodgy though.

realistic hemi question-what to put it in ?

I'm seeing a lot of the early Hemis for sale, and there appears to be many more on stands running, than actually in cars running. The major hurdle with an early Hemi appears to be, there is a shortage of cars to put them in. The 50's cars they came in are generally very heavy, and some have undesire...
