[Fot] TR3 / 4 Piston to Wall clearance

[Peter Vucinic]

Steve,

What clearance do you have now? What is the recommended STD clearance for
the Helpolite Piston? 3 to 4 thou? 
If you use this information to determine the fit, along with what Kas has
suggested regarding turning the sleeves, that's a good start. At least you
will be placing the piston thrust faces on a part of the liner that should
be pretty good for size/fit. As long as the liners aren't scored heavily.

Cheers...
Kind Regards
Peter Vucinic

I have a well used race motor in the machine shop.  It's got Hepolite  
Powermax cast pistons and 87mm sleves that have seen many races.
The liners may need a bit more than a light honing to freshen them  
up.  What would you accept as the max allowable P to W clearance?
I don't really want to buy new liners if I don't have to.
