T-Rex cam help
T-Rex cam help picked up a 98 ls1 motor with the T-rex cam already in it. Got rid of the 806's for some 241's with a set of prc .660 springs. i do plan on spraying this motor and was wondering about milling the heads and head gasket thickness. right now the heads are untouched and i have the gm ls7 head gaskets. i have a set of .045 cometics laying around and was thinking about milling the heads since i still have the motor on the stand. i was just gonna leave it with the stock heads and gaskets but was doing some research and see the t-rex likes more compression. looking for some thoughts and opinions. also this is a carbed motor with a super vic. thanks in advance
PTV is very tight with a T-Rex, have one in my 99 with 853 heads. You would need to flycut valve reliefs into those pistons for milled heads. You might just consider some 243 heads, small combustion chamber will raise compression without sacrificing clearance..... Or keep the 241s, mill them down and go with smaller cam.
