shaving stock pistons
« on: June 09, 2014, 09:24:32 pm »
Hi I know I have seen it before but I can't find it, when shaving the pistons for long rods what's a good thickness left between the compression ring and the top of the piston? My compression ring is .045 and I have .055 left to the top of the piston, is this okay?

I like the same amount as the width of the ring land, or more above the top of the top ring, to the top of piston.... so I would say your good. I would worry about the thickness of the top of piston, after shaving though, depending on which piston you are talking of.

I am running the stock 35 ci piston with the dish, the thickness in the middle didnt change, so .055 I should be good? And while I'm at it I will run stock rockers, flat top pistons and the cheetah grind, what's a good amount to take off the heads to avoid the valves touching the piston?
If it as a risk should I lower the compression ring and run two rings? Thanks!
