440 six pack pistons and some questions

Take a read through here:

'Pop's Engine' another 440 on the dyno.

If you're not familiar with reading IQ52's posts, he does LOTS of 440 stuff...this was his Pop's engine, and if I recall correctly, a 440 with those same pistons

I will check it out, thanks

Speed Pro says .002" piston to wall clearance for that piston, and 7cc's for the valve notches. the performer is a great intake

Ok great, so tell the machinist to leave .002 piston to wall clearance, got it
