12.5:1 572 stage v heads in a street/strip car 5000plus stall and 3300# race weight. Card suggest 106 install, but what do the Hemi guys think?

50 years ago with the R-292/294/296 cams, we installed them at 102.
On a 426 SS/A and AA, and A/B MP packages, both the 426 and 400 inch engines.

That’s at the valve, zero lash.

sounds like a good place to start with it, if you get 107 to 105 ILC run it

I like to put them in +2 to +4 so 106 on a 110 LSA seems legit to me.

It degree'd to 105.25 using the intake open .050@31.5* as is on the card. Should have ended up at 106. Thought i would ask for some opinions on subject, because i dont know what N/A Hemi's like. I understand N/A Hemi's dont make the torque as a comparable wedge, so thought maybe this combo would like earlier opening to help with the torque.

Your cam looks like a popular cam that Ray Barton uses

Cool. I ran the duration specs by Bullet and they agreed plus added the rest of the specs. I hope its a good one.

That big Hemi is going to make some serious power! That's a decent sized cam.

I check both lobes at .050 before max lift and at .100 and.200 before and after max lift also, I'm a little anal on motors.
I also check the exhaust lobes the same way to make sure the cam is ground properly. I have sent more than one cam back do to the exhaust lobes being ground on a different lobe center than the cam card call for, IE 110 LSA and the intake is at 110 with the exhaust lobes being from 111 to 113 BTDC at two different checking heights
They're correct or they are not

+1

At the moment not sure how to check that, but i will figure that out and give it a check. Was it Bullet that ground your cams wrong?

I was at Sonny Leonards one day and he had one of those cam checking gizmos. That told me he's bought a cam that wasn't right before. I wanted one, but when I checked the price, I had to step back. Even though I'll pay about anything for a fancy tool, I couldn't do it for a guy that builds a motor every couple of years.

I will be sure to check that out. Wanted to get opinions on proper degree install as i understand hemi's lose alot of fresh mixture out the exhaust valve before it gets a chance to close. Thought maybe it might need something different because of the intake to exhaust valve arrangement . Thanks

No, two were custom grind Isky, one was a old Racer Brown before he died and one from Comp Cams after they switch to the new machines and maybe a General Keneitics (SP?) or a Cam Dynamics CRS
You check the exhaust lobe the same way you check the intake lobe in relation to TDC, when you advance the intake lobe to get max lift closer to TDC you move the exhaust lobe exactly the same amount away from TDC
If it is ground on 110 LSA and installed at 106 ATDC ILC then the exhaust lobe center should be in at 114 BTDC: scope:
If you get 106 ILC at .050 before and after max lift on the lobes and then see 106.5 at .100 before and after max lift and then see 107 at .200 you got my kind of luck

LOL! OK. Thanks cab
