Patrick nailed it in another thread, I think: anything over 400HP flywheel is gravy in these cars. It can be fun gravy when there's a lot of it, but unless you're a straightline numbers fanatic the diff between 400 and 500 isn't going to mean much.
I'm making somewhere around 450-460 at best and it's satisfying, all I can reasonably handle and extremely driveable. I hope to smooth out the response with some detailed carb tuning but don't care where the HP goes in the process.
I'd love to be able to boast a truly original engine.
