Thanks for all the input. The stage 6 heads I have are not the old castings that had many issues but they are not Chapman heads. I will check out the links listed above and I wasn’t aware of the MP tip’s section so I will check that out.
The last 383 I built was 30 over with the old TRW domed pistons, stock rods, forged crank all balanced. MP .528 mechanical cam, roller rockers. The heads were a set of ported 452’s milled down to about 84cc’s. TM6 intake with a 750 double pumper. It ran 11:90’s in an old 63 Plymouth that I think was around 3600 pounds? 4.11 gears and 28x 10.5 slicks. 727 trans with manual VB and 3000 converter. I drove it quite a bit on the street and only had it at the strip 3 times.
I was thinking about replicating that build with a bigger roller cam, the stage 6 heads and better intake. How much RPM can the stock rods take?
