360-508 mopar cam builds

I have a similar 360 combo just built.
360 LA fresh .30 over, stock crank, new Indy "Dart" J casting heads 202 and 160, MP purple cam, KB quinch pistons, heads and block decked, .60 head gaskets, 750 Holley DP, Edelbrock intake milled .70 to fit, 373 gears with Richmond locker...stock 727 with stock 727 TQ (1400?) and I ran it for the first time a few weeks ago...15 second quarter.:violent1:
I know I can get another second out of it with tuning. Desperately needs higher stall converter! Very doggy under 3000 rpm then comes alive 3000-5500.
Just my combo...hope it helps.
