Off the shelf (not FM) 83.5mm 8.6:1 wisecos. About to send pistons and block off for machining.

Goal is 325-350whp. Im thinking. 0035-.004 will be good for my application. But want to see what others are doing

Whats your piston to wall ? And does it slap ?

I honestly can't remember mine but it was whatever wiseco recommended which I believe to be .0035. I get very very minor slap on very cold mornings and practically none when it's 60* or warmer outside. I have run this clearance for 6 years now with this particular engine and I don't consume a bunch of oil and the engine makes good power and has been happy.
