combine them with my LT1 cam work with the computer, wont need expensive springs, will make MORE power with a proper tune but if your car is a MAFS system itll compensate pretty decent and be a heck of alot better then stock 60$ shipped

i also have a set of vortec heads you can get them milled to 60 cc and have them rebuilt(i have everything but springs for the rebuild including locks retainers valves and seals, the valves are manley race flow), ill sell everything for 375 youll need a scoggin dickey lower tpi manifold

 

got rid of the cam still have a set of vortec heads

 

I have an LT1 cam as well $60 shipped
