What Carb for Poly Stroker

66 Sat,
You choose what you like. I have been doing this for 50 yrs. Yes, not an apples to apples comparison. The Charger v GT test pitted a 625 cfm carb against a 830 cfm carb. The extra 200 cfm didn't do much, as the GT was slower in acceleration. During the muscle car era, 4 bbl Chrys cars were head of the pack for performance.....& they had AVS or AFB carbs.

When the popular small blocks were tested in 1969 to see if their developed HP matched the adv hp, only one engine did: the 340 & it made 20 hp more than adv!!!!!! Nearly 300 hp with a little 625 AVS, factory exh manifolds. The Ford 351 made the lowest hp & guess what carb it had...

That's because Chrysler under rated the 340 to get it into the class with other small blocks, but NHRA soon recognized that the 340's were better and 'factored' them into the higher class with the 383 & 396 big blocks...

Or as an old friend of mine, Hemi Greg, used to say, "340's are small blocks that don't know it"...
