Yes using small stem titanium intake and exhaust valves to keep the weight down and a new cam with more exhaust duration and lift, intake lobe will be similar to today's 281@ .050 and 297 @ .050 exhaust both right around .800 lift
a little more aggressive ramp in the middle. Using the very best NASCAR springs this time. The old engine pressures were still at installed levels but thought I should upgrade because of rpm. They are supposed to be better material. Individual roller rockers and .125 wall 3/8" trend push rods. !5 to 1 compression ratio with smaller chamber and a slight pop up on piston. Trying Line to Line coating process on pistons too. The crank should be a work of art according to Kinetics. Head flow is around 380 cfm so that is the limiting factor although we will do some manifold work too. Installing a modern EFI this time with traction control because it is legal now in Goodguys.
