The Best V8 Stories One Small Block at Time
I hear ya on that! I just got done puttin on an f1a and had to do quite a bit of "massaging" to get it to work.
Good luck with the build!
Ford boys have run low 8's with YSi's in 3200-ish race cars like in the NMRA Renegade class. I know they have run 8.5's, maybe 8.2's? That's with less than 350 cubes and with like 26-30 lbs of boost (off the top of my head I'm sure someone knows better).
So I'm thinking that somewhere around a 80-88mm turbo would compare, though turbo selection is also dependent on engine displacement.
NMRA Drag radial pits X-Trims against either 85 or 88mm turbos these days.
