Well got the first hour out of my wiseco 4.125x 4.070 ls3 with TEA ported heads mild cam and a carb on top. Engine is quiet oil pressure 80 at start and 60 warm. None of the noises that have been mentioned on here so far when having such a long stroke in a stock block. I guess we will see how long it goes. Just thought I would give a good news for a change.

I have a Wiseco 4.07" piston for my 4.100" crank also. Never have had any noise or slap or whatnot from this iron short block either.

It is a great piston for a long stroke package.
