I'm currently rebuilding the engine in my 65 xp, block all done, new cam, crank and timing gear in, just cleaning up the pistons and need to know how to tell if the gudgeon pins are too worn, i got told if you hold the conrod tightly and try to rock the piston if there is any slight movement, then no good, the piston top slides side to side very freely, a little to easy i think but i don't have any rocking movment, the book tells me jackso how can i tell? really want pistons in soon.

yeh mate hold the rod and try to rock the piston sideways following the pin. id just get them redone anyway. i put ACL flat tops in my 250 2v in my xp. made 152kw(200hp)@ the wheels

yeah, probably best to get redone, they are already 15thou over flat tops, stage 2 street strip cam, wild cat extractors etc. do you have an electric dizzy? if so where did you get it? also i'm after straight cut gears, i work in an auto parts store and none of my suppliers can source them here in SA do you have any ideas?

nah mate im not into straight cuts and yes i have an electronic dizzy. its a XE crossflow modified to suit pre crossflow and graphed to my cam. done by Jerry at ignition torque in melbourne
