Im trying to figure out what size pushrods to use still?
It has ls7 head gaskets and I need to know if my 7.4s will still work.

I know its not the best build but this is my cruiser for the summer while my racecar is getting completed.

thanks indvance.

p.s heads are stock not milled and ls6 springs.

the ls6 cam has a smaller base circle the ls6 valves are longer to accommodate this so while 7.4 would work 7.425 would be ideal. i would measure to be sure though
