I bought a complete 360 short block, unassembled, from the local machine shop. The previous owner is in prison, won't be needing his engine any time soon.
So I got a H.... of a deal.
The pistons are all new, KB hyper. I know what some of you are mumbling. I have NEVER run them either.
WELL. .... one of the pistons has one of the pin bores with scuff marks lengthwise with the pin bore axis. I asked a second machine shop and the crank grinder/balance guy what they thought. Everyone thinks it will be ok.
The car's not going to be a race car, just run on the roads regularly, but we are supposed to build a bullet proof bottom end for our engines.
What do you guys think? I can always change it out if it starts to rattle, and you know how it is trying to build a whole car, the cost keeps climbing.
Any suggestions of preferred piston brands? The build is relatively mild, maybe 400 hp, and will keep 6000 rpm or less. So I don't think I need forged, and they rattle so bad on start up here in the cold climate.
But I am truly open to all opinions.
