Like a few guys here who race 98% of the time in auto cross and a couple of road race tracks, I am going with a dry sump setup. Getting the sprayers to hit the correct spot will be the question. Main concern is amount of oil and loss of pressure with 8 sprays working.

I don't think that some guys understand that the 100# spring is for MAX pressure to the motor on cold starts and starts bleeding off anything above this number. On cold starts my oil pressure guage is 125-128 psi. I let the motor warm up without any throttle input. Takes about 2 minutes for pressure to be in the 85 psi range and drops to 75 after a total hot soak of the motor. Cool down with large fan and back to the 100+ numbers. I do have a oiler that is .010" in the oil gallery plug location behind the distributor that sprays at the 2 gears between camshaft and distributor gear. My end play for the camshaft is .003-.004". Hot I have no measurment. There is no movement and the thrust plate and torrington bearing are the original with 15 years on them also. Not turning higher rpms does extend life of motor and parts. Buying top parts and knowing their limits also helps.

Your magic motor will have about 150 hp more than mine but about only 100ft of torque in the mid range. ( my best friend ) You will be quicker but mine will live longer,. Rick L student of the cobra motors. Ps your car is worth $,$$$,$$$.**. My car is 10 times less the value. We both are having fun. The next thing is getting the suspension to work as well as your car in handling. Diet and losing 50 pounds will not hurt either

I should have some good info for you soon, I am experimenting with front roll centers this weekend from 1" to 3" above ground. The handling keeps improving, I only wish I had put this set up in for the 50th anniversary at Laguna. Just bought a new Tilton starter and boy does it have torque, you could drive it in the trailer with the starter!
