John,
I apologize, I thought your were confused about the FF33 build, as I did not take (and have not taken) time to go to the other hot rod site linked. I was only going from what had been said here, and it seemed to be off. My mistake.

Regarding a deuce and "necessary" power, my '33 highboy coupe is pushing about 425Hp and 475ftlbs, and I can tell you it is a handful to drive at WOT. Fun?? Sure, I love every minute in it, but if I were doing it again I would likely go with a much more sedate crate engine in the 300HP range. For me the added power of a big block is going to be severe overkill in a light vehicle like a fiberglass coupe. The added weight up front is going to affect your handling, and unless you're going to have it built for hard core drags or nostalgia gasser wars you're never going to need that power. Now if you're wanting it purely for the "WOW" factor, more power to you (pun intended). As a cruiser I'd bet you'll be much happier with a nice small block without too many bells & whistles other than the desired bling for the open hood look. Just my $0.02 on the subject, and you can take it for what it's worth.
