410 LA small block will not rev past 6000

Ok, first off, what happened to the Mallory ignition?

Aside from that, you have 410 inches, your heads are undersized and your cam is way too small. I’m surprised it will run to 6k. It’s out of air.

Do you have graphs of torque and HP? If so, can you post them up??

I’ll run some cam numbers off of it if you do. That should be fun. And interesting.

Ok, I see the graph. It doesn’t have RPM on it. We need that RPM.

I was afraid the cam was too small. But it does make me feel better thinking it may just be out of cam and not something "wrong". The car is a blast to drive, makes allot of lo end.

We did the best we could with those Eddy heads porting them and the larger intake valves, at the time was not many choices that I could find. I see Trick flow has heads now, I have always had very good luck with trick flow on other applications. Are the trick flows currently the best option for small block Mopar?

Ya the Dyno print out is in MPH, I could always dyne it again. I could also calculate the RPM off of Tiresize/Gear but it would not be exact because of tire growth, and when strapped to a dyne they get squashed down anyway.
