On a SBC w/mech roller. Anybody have this done? A guy I work with looked at my engine block that's on the stand waiting reassembly and he said it'd be a good idea. Also opening up the oil return holes in the back of the lifter valley. I "Googled It" and found a few different sites where it was discussed. It's supposed to force all the oil to fall to the back of the pan and prevent oil from falling on the cam and crank and causing windage. What I read was you could do it with a roller but not with a flat tappet, but some said they'd done it with both with no problems. Others said "GM put the holes there for a reason!" The guy I mentioned earlier went to The School of Automotive Machinists(SAM)in Texas and does engine building on the side and said he could do the work for me for $150(parts&labor/new cam bearings). I agree with him about opening up the return holes but I'm unsure of the vent plugs. What do you guys think? It is a race only engine so wouldn't be any street miles.
Thanks.
