Small block chev is a small block chev. If its in a corvett, its a corvett engine, if its in a truck, its a truck small block. Most vetted just came with regular old small blocks, maybee a bit better cam, its not till you get into things like an LT1. 2.02 heads, SOLID lifter cams, forged cranks, stronger rods and such. Having a corvette 350 means nothing. I have a motorhome sbc 400 in my blazer that will wax a vette 350. Get over the Corvette option. Gm did on ocasion put hotter than called for 350's in vehicles, by mistake, at change overs, or when thay ran out of what was called for. I have a buddy that worked at a GM dealer back when our trucks were new, and he found a few of these. He tells me that the owners of these vehicles, would come in complaining that the engine didn't idle as smooth as his neighbors. So under warranty the would change out the Corvette camshaft for the smaller cam.

as it turns out these motors were in fact put into 72 corvette's. But the rated HP was not much around 200. If you wanted more the LT-1 was the option. So im sure a ton of these motors are floating around.

this guys vet has the same heads, manifold and carb as my Jimmy. So its a plan jane motor.
