I have a 350 4 bolt main with 2.02 double hump heads, edelbrock performer manifold that sits in my 1970 chevelle. i looked up the casting numbers on this engine and it always came up as a 69 or 70 LT1 engine. i also put the heads casting number in and that came up as part of an 69 or 70 LT1 engine.
i am looking for a cam that i can drive on the street and go to the grocery store. i want to give my car rough idle like a pro stock sound, but also have low to midrange power.

Without knowing your stall speed and rear gears I'd say an Isky Mega 270 will be your best bet.
