Stock ls1 head vs 5.3
Okay I am wondering. Does a 5.3 head flow better then the head I already have on my car its a 98 Z-28. I plan on gettting a set of heads that came off a truck that is ported and wanted to know would it be worth the swap. Also what will be a good cam I want to spray 100- 150 shot wet. Ima thinking I can go ten's easy with all the bolton's and the head & cam swap.

5.3 heads when ported and milled flow good and bump compression. I think heads and cam and spray will get you there. Just have to have correct suspension, tires and size, a 12 bolt or 9 inch with proper gears and the list goes on. For
A real 10

Have you guys seen some good dyno & 1/4 mile times with the 5.3 heads and a cam on nos and motor. What's the best you have seen with a bolt-on car with just cam and cam & nos stock heads and bottem end.
