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 ...

Paul- thanks for the realistic advice.

Re: Help ID this 270 Hemi or Poly or other?
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.

The Chevy has nicer lines, the Stude looks more like a school bus in the back window/seat area, squared off.

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 ...

Does anyone think they can help figure this one out? Let me know! The 1635729 casting on the block translates to 270 Hemi per my database. 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...

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

I ran across a reference to knurlizing pistons for a tighter fit in the bore. Is this reliable? How much expansion of the piston is practical? Would you still measure piston clearance in bore with a mic/snap gauge or feeler gauge? When I read about it the thought occurred to me that if my cylinders...

thanks for all the replies, haven't checked the thread for a while, since then I've sold all my 331's, obviously the 392 is the one to build for max power naturally aspirated- so now I'm keeping my eye peeled for a 392
problem is, those are the hardest to find at a good price, and the most expensive
