Maximum Performance N/A 383 build. Input wanted from engine gurus.

You have picked the worst engine out of all the big blocks to power a heavy car; the 383/400 has the highest rod/stroke ratio of ALL the BBs, 1.88.

Far better to go with a stroker crank & use 383 rods [ H beams ].
The warning below about too much duration causing slower ETs applies to 383s as well as 440s.

yeah, well the car is a factory 383 car so I think it's pretty novel to have the original block, trans, and rear end housing in a racecar and make decent times.

It's not like I'm trying to go class racing or anything, I'd be tickled if it ran in the high 9's/low 10's with a shot of nitrous, and 11s N/A
