Those two know what they are doing it’s a good start.
I took us 4 days to figure out what the dude did...but he now knows for sure what the combination is. I have to give the builder a little credit, he did put some thought into it. If he hadn't flubbed the pistons to valve clearance it would have run fine.you've got too many threads going for the same build . I thought you said 6.2 rod in other thread . either way I think your chevy piston can be cut down to 11:1 and work with your cam head combo na but not with boost . call rebco and see what they say or order a new set with the compression you want .
I use automatic transmission fluid, keep doing it until lint free towels are free of grit, helps prevent rust also. Then I clean that with wd40 before assembly and lube with a small amount of oil, but I'm just a hobby engine builder.Back at it.
Before installing pistons. What do you wipe the cylinders down with in case they have dirt or debris? Just a towel? Any solvent?
I thought the short block was good too. Dont understand why he didnt eyebrow the pistons in the block and call it a day.I took us 4 days to figure out what the dude did...but he now knows for sure what the combination is.

LOL. You were all over the place on this engine. Maybe procharged, maybe 12 years from now, etc etc etc. My point is that it would have ran fine with a little work on the pistons.You're asking him like it was his motor or im retarded. However I'll still answer you.
The pistons were 12cc dish. You can't run that blower on 12:1 compression in this application. That was made very clear by procharger when I called them. In order to get reasonable compression ratio I needed to have a different compression height as well as a much larger dish in the piston.
Now im down to 9.27 static compression, 7.75 dynamic
Better suited for 91 pump gas with a blower
It is recommended to not run more than .060" quench, and the thicker gasket would have put me much higher than that.Got it. I solve the former with MLS gaskets, not expensive, easy and it works. The latter does require different pistons or a dish cut. Cutting a dish is easy and cheap.
I didn't end up getting a new one yet. I got three different quotes for a custom grind and they seemed to be pretty vastly different, so I'm still trying to learn myself a little more about cam selection before I make that decision.Glad you’ve made progress.
what are the cam specs ?
