hey guys just wondering if anyone might know how much HP a stock 350 has and how much HP a set of 327 heads will give me on that same motor the heads casting # is 462 I will be patiently waiting on your response :banghead:

Okay, I'll bite... Which 350? Do you have a "pump gas" requirement?

For any performance 350 (factory), you will LOSE power going to the older heads. They (327 anything...) were obsolete in '69, when 041 was introduced.

What exactly do you want the engine to do?

first of all thats bull my father did the same thing and his camaro ran 3 times harder than it ever has it gives it better compression it might not work on the current engines but i know it will on my 1970 350 i was just wondering if any one knew how much hp it would give it check on it dude then hit me back :screwy:
