Or a higher cumbustable mixture to get it moving faster?

I can't find a proven specification for the 220HP 283 other than 4 barrel carb in general descriptions.

Then there was a dual-4bbl 275 HP Corvette engine I think.

OK - not ready for that!!!!!

Why a 283? - that's all I have.
I have considered the 327 crank but I don't think the 1965 block will accept it.

The old 283s had WCFB or 4GC Carbs while the later engines (up till 66) had the Rochester 4GC. I think they were around 485 CFM The Dual four 283s came in 245 hp or 270 hp. The 245s had the hyd cam while the 270s were solids. Dual fours on the 283 ended in 1961.
