Good info. I am not using this motor as an oval track only, but definiatley want a good oil system. I just put the crank in, and from a plastigage, i got a little over .002. the thrust bearing was a little more than the mains. the mains show closer to .002 that .003. ~.0023ish i would imagine.
Is the melling hv oil pump (#m55hv) good? i had it in my last motor, but some say that it was partly the cause of my stretched timing chain.
