I just bought a eagle forged 383 crank with 5.7 "esp" h-beams for floating pin pistons. Now I was looking at SRP 4.030 -16cc inverted dome pistons. I am trying to keep my c/r around stock level and with these on 58cc stock ported/polished head(2.00 I, 1.60E valves) I'll get 10.4:1 c/r. I am looking at making 350-400 h.p.& torque at the flywheel. I'll be using a lt4 hot kam kit.
Question is are these pistons made for floating or pressed fit pin set up.
This is the piston from Cnc-Motorsports "383 4.030 3.750 5.7 1.425 10.4 9.8 9.2 -16cc 457 ". Here is the link http://www.cnc-motorsports.com/produ...599&CtgID=8206

"Pin fitting and double spiro locks included"

They're floating. Spiro locks go on the end of the pins to keep it in place.

 

Same pistons I have except mine are for a 6" rod. Try adperformance.com, he should be able to get you a better price on them.

 

Thank You
