Just curious, as to what everyone does on a refresh.

I've got a 355 with 8 races on it that I have to swap pistons out on due to compression rules. Do you all keep using the rods if they are good, turn the crank? Hone the cylinders, swap out bearings? Hot tank it? Change cams?

Before a complete teardown I inspect a few things for wear. A compression check every now and then will show ring/cylinder wear over time as will dropping oil pressure. If the motor's out, pulling the pan off and checking a main cap or 2 and a rod bearing or 2 is a good idea. I had a motor run the whole '02 season and it looked fine afterward. So it went back together and ran all of '03 with no noticable drop in power, oil pressure or compression.

I don't rebuild 'just because' since it's too $$$ for my budget. If there's no sign of a problem, why make one by taking it apart? Now if oil pressure or compression are dropping, it's coming apart for repair. With gaskets being $100, rings another $100 and rod & mains being $100 I'm not much for dropping $300 'just because'. I'd rather buy 3 new tires or a couple new springs and shocks. They'll make more of a difference than a 3% increase in power from having brandie new rings and bearings.

8 races is not alot,if it's a claimer style i might even reuse the old rings.
