Anyone using a P4452782AE on 340/360?

Get the compression up some and advance the cam down to 108 or 106 ICL.

I was planning on advancing it 4 degrees.

to much duration with 3.23 and stock compression
stock piston or has motor lower end been rebuilt?
this is a low lift- low area under the curve cam
seat to seat duration is more than the 268 (designed for a chevy lifter) comp which is also too much duration
do you have compression check numbers?
good news is that MP cam lives forever and it's fater than it looks and works with stock 340 type springs
need to get a handle on your compression before any cam comments
headers? AT or 4 speed etc, carb and manifold?
check Lunati Voodoo line
and some howards the real mopar cams are flagged in the catalog also some Bullets
Engle has a good line if you ask as does Crower
comp not so much

The lower end was completely rebuilt but wiped a love on the cam after a minor comedy or errors :/. Now I’m back searching out something better than stock. I’d heard the 340 cam being suggested but never had good numbers to compare.

Nice. We’re they milled at all?
A half point increase will help yield good results with a iron head. Generally, with a small cam, I don’t like to go past a 9.0-1 ratio. Going higher isn’t a octane issue until you get that bad tank of gas.

I had the deck milled more then a clean up and same with the heads. The headgaskets I have are nos 3512719. Hopefully that get me there.
