Went with Holley efi and flex fuel so will be running E85.

Because of that I ordered .027 Cometics and milled the heads for 12.4-1 compression.

Got the accessories figured out. Ported the intake and drilled the intake for rails (drilled the rails as well).

I would still work outside if that was my garage (cleaner than my house) would be afraid of getting it dirty

Very nice, both the building and the hemi. I have racking over my tool boxes similar to you but some dummy (me) set that shelf too low and I bang my head on it when I look in the top of the box. Have to fix that before blood is shed. whiney


In theory, there is no difference between theory and practice. In practice, there is.

and what fun would that be ? biggrin
my tool boxes are positioned similarly, and it's ALWAYS fun "rubbing" the hair [what's left] off the top of my head. laugh2

Coming along very nicely up

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.

Good deal I'm glad you didnt have the same issue, I could not tell from the pics if yours was cut as deep as mine on top or not. I really liked the looks of the morel lifters . It was the world block , wedge head on my old 65 belvedere. They did get carried away on the countersink cut at the top of the lifter bore on mine. Lobe lift on that engine was in the .450+ range if I remember correctly. I just got the KB block back from machining for the hemi. I went ahead and had lifter bushings put in it with a .028 oil hole.. I have the same tone wheel, cam sync etc. that you have. I got everything from Rich Nedbal including two accufab throttle bodies. my intake is the stage V. I am still in the mock up stage though and quite a ways behind you., wiring, plumbing etc. I have a couple of cams I am going to try with the Efi I am putting in the 262/270@.050 Lift .710/.690 on 114lsa. Also have a 270/276@.050 .704/.690 on a 112lsa we may try down the road. My wife is in love with that Caddy by the way.

Dang my lifter's look short next to yours. If it hadn't been together for 10 years I would be scared they wouldn't work. Lol

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.

second 70-

Not to far away from my cam! Events on mine are

IVO 24
IVC 58
EVO 68

I'm ready when you are to tune that SOB!
Great progress..I normally use the Crower Enduramax lifters that oil through the pushrod as well as high pressure to the roller. Never had one fail. Keep the pics coming.

Thanks Rich! Too many projects so working at a glacial pace....

Turning out really nice. anxious to hear how Rich's tuning goes. I'm plugging along but your glacial pace is making my pace look really slow.

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

Is that a red Ferrari in the backround?

Jeez, a hemi AND a Ferrari, I feel so inadequate...LOL

Good for you!
