Cool..... Found a used set that I want to put in my old ratrod to up the compression that has a late model truck engine.. Just trying to keep the cost down

why bother?

The pistons are way down in the hole, compression is crap, It's way over cammed but sounding angry and oil pressure is down ... I had the 906 heads redone and hardened seats put in. The cylinder walls looked perfect. Engine was out of a motorhome... Just wanting to put new bearings in it and freshen it up .. Thought I would try to make it a little stouter and more fun by getting away from the 8-1 pistons in it

Six Pack pistons are cheap.
