hi, its me again.

which piston to wall clearance is for street use with the speed pro flat top .030''
pistons (L2320F) the best option and why?

its a 350 olds , 1977.

thanks a lot.

 

When I couldn't find information on the Speed Pro pistons in my Olds, I called their customer service. The representative had specs on the piston and provided the information I needed on the dish. It may be worth a shot.
