Okay, here's a new one on me... The mechanic who has worked on the K5 Blazer for as long as my grandfather owned it says that he usually puts heads meant for a fuel injected 350 on his carbed motors because they are an inexpensive way of getting a better flowing head. /forums/images/graemlins/confused.gif I understand the better flowing part, but is this just an old trick that I have never heard of before? If so, what heads are typically used? Can I just use heads off of a newer model LT1 with my pre-1986 block, a custom cam, Edelbrock intake and carb? If this is a cheap way to get more power out of the engine, I am all for it. Someone please fill me in on this.
