jrbnc,

What a great opportunity! Pull your motor and find someone to help you go through the lower end and clean up parts.

Have a machine shop or better yet a race shop give your head a good 3-angle valve job and surface the head. Have them remove any sharp edges off the pistons and combustion chamber and set the piston to head clearance to 0.035".

Get some Total Seal rings for your pistons. And get a race quality bore hone and prep.

Assemble and have a ripping motor that will be dead stone reliable and the cost to do the above is most likely cheaper than buying a used engine.

Be prepared for about 40 extra Hp.
