Re: engine knock

Joe---Piston slap would be my guess for your cold engine knock. Some
rebuilders insist on more running clearance than necessary for the
stock, cast aluminum pistons. They do warm up quick enough and quiet
down. If you can contact the builder, see what clearances he used.
Standard clearance is around .002

If you installed the forged type of pistons, more clearance and slap is
customary.
