The best option for the extended block is a manual trans. The current crop of auto adapters are not exactly a bolt-up.
The engine itself, even with the small valves and smallish ports, can still make respectable power if you bump the compression to 10:1 and use a decent cam.
As for the 354 and 392, they are alot more money up front even though the adapters have wider range of trans options.

I agree from what I have seen that number sounds just about right, but everybodys got a sbc.

Bummer...that lower housing is very important. I have seen, and bought, pieces on ebay, but the listings are sporadic at best.
Expect to pay as much as $150 for one.
I would deduct $250 from the asking price.

Nice! The beauty of the Chrysler hemi is that even though the deck height differs among the engine sizes, all the intakes fit. They made up for the difference in deck height with the heads, not the intake.

You do realize that owning a Hemi is a incurable disease...
Glad that you found the housing.

I am learning that quickly. Looks like I gotta find and intake of some kind other than a 2bbl and a trans adapter and flywheel for a chevy 4spd. That will be a good start.
