I prefer small blocks, just because I prefer them. LOL
I'd like to put mine in a feather weight car and see what it would do, it's been 135 in my 3292# Dart, on pump 93. It really doesn't fit the spirit of discussion here though as it's 434".
I have a 406 that a semi-smart chimpanzee could put together, in a 2300 lb car. Went a best of 6.32/108.5 with maybe 500 crank hp
I'd guess your 434 at around 650, so.......very low 9s at 145 in my car. Maybe a high 8.
