thanx luke but it is a little too far.
well i pulled the motor tonight.found my slightly low boost issue as the passengers up pipe slid right out of the collector.popped #1 piston out.its melted not hammered so the chunk of nozzle wasnt in the cylinder.only thing i can think that may have melted it was driving for a couple weeks when it had the fuel knock before the nozzle finally split.#5 has what appears to be bubbles in the top of it indicateing that it too has seen some high heatstill havent found the coolant issue yet.i havent pulled the other head yet either.but the crank and bearings look almost perfect.no evidence of a bent rod,they all look straight.
what is the max oversize that i can bore it to?will it be ok with a .020 overbore?tomorrow if i have a chance im gonna completely disassemble it and find out what it will cost me to have it checked for cracks and what size over bore it will need to get the scores out of #1 assumeing 2,4,6,8 are fine.maybe ill get lucky and the scores can be cleaned up and stay with a standard bore.i doubt it though.maybe i can get out of this with rod/main/cam bearings,.020 pitons/rings,oil pump and a gasket set
