Default 302 bored 40 over
I bought a 302 bored 40 over with pistons and crankshaft for $50. How big does that make the engine, is it now a 306 or bigger. I am not sure what heads and cam to get. im getting a cobra intake. i want street compition, so i can beat a bunch of ricers (no offense to them)

308 cubic inches if my memory serves.....

Make sure to have a good cooling system; 40 over motors can run a little hotter....

Mine was bored .030 over but a lot of mechanics I've been talking to tell me mine is still a 302. Are they wrong or am I?
