Priobe You are making this easier. The motor is new with 500 miles. Nothing is seated yet. The piston rings are not worn in, the valve seat and valves are not broken in to seat. You didn't say what temp the motor is running at. The motor is tight to start. I don't agree with Pat on the
oil pressure at idle. I just put a stroker kit in my Shelby block 482. I am using the same pump and
oil on the new parts. The new bottom end is tight but I still have 30-35 psi at idle, 850 rpm and goes to 80 before 2,500 rpm. This is a HVHP pump from Mellings. Go to the FE forum and ask about the rod and main bearings there. Barry R, John V, or a couple of the others are involved with FE motor since the 60's. If your
oil gauge is reading correct at idle IMO you will pound out the bottom end bearings. Call Barry R and ask what a custom set of pistons cost for the rods and crank you have. Tell him the cc on the heads. Get the compression up to 10 1/2 with the aluminium heads. Next look for a cam in the .600" lift. Look for a power range from 2,700rpm to 6,200rpm. A 112 LSA with a -2 cam retard after the cam is installed. Some cams come with a 4degree retard built into them. As for the idiot oil lights coming on at 4-10 psi, If you see this light the party is WAY OVER.
What oil are you running and is there any additives? 600HP is not easy to hit, I am talking REAL NUMBERS with a streetable 427 motor. My 482 motor is new and I hope to get it on the dyno in April. On dynosim and Dyno 2000 I am looking at 510 HP and 580 torque at the crank not RWHP.My FI system may cost me about 8-10hp and 5-8ft of torque over a good carb. My cam is a 587-607 roller. great power from 2,500 to 6,000 rpm with a 6,500 rev limiter. The ford number for the nascar rod bearing is C9AX-6211E or F. You could try Rich Kirk or H&M for the correct bearings. I have heard they are very hard to fine. There are also questions about the nascar crank being crossdrilled and causing alot more oil pressure drop in the motor. I will catch you later Rick L.
