I am sure grizz, 22racer[anyone heard from him lately?] or mark from massive mods can give out the info.
Interesting with the wrist pins. I have never heard of any problems before.
I always slop lots of after run oil on anything new going into the motor. It takes a little time for the oil/fuel to fully penetrate something like the fine space between the pin and the rod bushing. If it's running dry for that initial period until the oil gets in there, you could be putting 5 hours wear on it in 30 sec when you fire it up for the first time. Same reason I strip down a new motor and lube everything then re-assemble before firing it up for the first time. Otherwise it's like starting up a brand new full sized car engine, waiting till it's running and then filling it with oil !!! (not quite the same, but you get the point).
BigMatt - let us know how those new pins and clips go mate.
