I recently bought a Sbc 350 block but i dont know what it came out of and the guys at the chevy dealer here cant tell me what it came out of even with the s/n is there a way to find out what year vehicle it came out of atleast and also i was looking at buying new heads for this engine but i need to know will any 350 head fit any 350 engine? all help would be much appreciated. If your curious as to what im building im building a twin turbo 350 for a gen 3 camaro
