Piston to head clearancing

[Ol' Ron]

Yes, this can be done with rosin core solder. However, it takes practice getting the solder in the right locations. But it does give a very accurate measurement.

I've never had to take more than 25 or 30 tho off, I like to get the clearance down to around 30 tho around the edge of the Distion, then shape the edge down with a Dremel, to 45.

It's importan to realize we're talking street engines here and forged pistons with large wall clearances are a different story. I build my engines with Egge 3 ring and fir the pistons to .002 wall clearance. Seems to work quite well
