Well its been a while since I have updated.

The build is as follows:

Stock forged crank. Reconditioned forged rods with ARP bolts. Melling HV oil pump. TRW 2399 pistons .060 over. The heads I got are stock HP500 Carb heads. They have Manley Severe Duty intakes with inconel exhaust valves. I used a crane 134561 cam with their matching triple springs.

I hope the 'triple springs' was a typo.

Motor looks sharp..

Its has 2 springs and a damper spring. For regular use Crane 99893 is ok. For extended high RPM use Crane recommended 99896 springs. They were $256 vs $89 for the cheap springs. It seems like valvetrain is not the place to try to save money.

I hope that was a typo on those springs.

The 99896 spring is for a hydraulic roller camshaft, and will have way to much pressure.

99896 is 150 psi @ 1.900,and has a rate of 528lbs lbs/in. With your cam, it would have around 450lbs of open pressure. That will kill the cam quickly.

Those are the part numbers Crane specifically recomended.
