Coming along very nicely What are the cam specs? Did you decide to go with pushrod oiling? (won't be offended if you'd rather not say)

I could not build oil pressure with the same Morels in my world block at full lift. Due to the lifter design with the side cutouts. It pushed oil out like a sprinkler at full lift prelubing with a drill., I could not see the cutouts but close enough to the top it caused issues.. You might check it if you haven't. It may have just been the machining on my block but a different lifter design fixed it. Just passing it on because yours looks like mine in the pictures. Nice build, appreciate you sharing it.. I am doing close to the same EFI on my 572 hemi using holley dominator ecu and smart coils. Galen

Thanks guys.
Before I ordered the cam I measured the reliefs in the oil galleries to decide base circle and lobe lift. With .428 lobe lift on the intake it's .100 away from uncovering the oil gallery on both the base circle and at peak lift. Lifters measure .9035-.9036. Lifter bores .9052.
I did prime it already and everything looks very nice. No problem getting oil up to the top and nothing appears to be a 'gusher'.
I am running pushrod oiling.
Cam Motion ground the cam. I asked for 268/268 @.050 on a 112 lsa. Bob ground it 262/262 @.050 as it's a low lash lobe (.010 hot) and he said that would be rather comparable to the 268 I wanted if it were a standard lash cam.
So it's 262/262 @.050 112lsa .428/.421. Measured .658/.612 at the valve. I installed it at 107 ICL. PSI 1575 springs (1.4" OD) with Xceldyne ti locks/retainers. Intake 245lbs at 1.83 on the seat, 613 open. Exhaust 256 at 1.81 on the seat, 598 open.
Galen I suspect you are running a bit more lobe lift than me. It would help if the lifter bores didn't have a huge chamfer on the top. Yours sounds like a nice build! I'm going to try Ford Coyote coils.

Galen, I bought my parts from Rich as well. My vote would be for your 2nd cam considering your engine size. And thank you, the Cadillac is pretty beat up but it's a good old car.

Yes the boots have to be shortened a bit. I'll get you a measurement.
