Clois Harlan Clois have you thought about getting the crank cut for BBC rods? The bearings are wider and may last longer. Dry sump may be needed for your racing. You are running BB perpared. It maybe time for a 500 cid motor that will make more power, less rpm, last longer and a lower gear for those long straights you are talking about. I think a call to Georgia Moon, aka George A is needed. Do you have and accump on your car? I would look into this also. Hotfinger you are running a chevy which have the best oiling system in any motor made. These FE motors have one of the poorest oiling system except or the side oiler. I splash system to
oil roller lifters is not for regular driving, we all know this. Some people have luck with parts that are for racing only and drive them on the street for 10K and never have a problem others drive 1K mileage and the motor is trashed. dlampe I don't know why hydro roller lifters, lighter valves, and a 600" cam is not the answer. The beehive comp springs sound good also and rev to 6500 without problems. This is what a am looking hard at. Nobody has said how much more CFM flow is going on from 600 to 700 lift. 20-40 cfm? this is good for nascar or 1/4 racing only wide open throttle. Hows your car doing? I hope Santa gets the parts you need to fix it
Have a good holiday
