Mopar purple .528 for a 383?

I couldn’t pass up the price, and I might be close on that compression ratio with the flat tops and small chambers.

I have no other ambition for this build than to sound good, look cool, and do big Smokey burn outs. Which should be no problem with the 4 speed and 3.91’s.

If it’s too much for the 383 I guess I’ll just have to get a 440!
In this 383 build they compare rpm vs victor at 3700 rpm 480 vs 453 lbs-ft lowest they dyno.
