Best piston for street/strip 340?
Here's an option from SRP.
I don't know your budget but build what you want. To many of these cars sit in garages as pipe dreams. I'm using the heavy slugs, eagle forged crank and I beam rods. My rev limit is 6400 and I shift at 6000 with no issues.
I won't use a hyper piston. I dropped an exhaust valve on my 360 magnum and when the piston shattered the motor was toast; wrist pin punched 2 holes in the cylinder.
