Which motor combo would perform best with a stock 350 Holley carb? It's a farley wide 1/2 mile dirt track. Car has to weigh 3000 lbs

355 6" Rod 12.5 to 1 with stock double humps 2.02 & 1.6 and a stock Weiand X-celerator intake. Motor would turn 7000+ RPM

or

406 5.7" Rod 12.0 to 1 With Stock Vortec 1.94 & 1.50 and a Stage 1 Brenzski 4 barrel intake. Motor would turn up to 6300 RPM.

the 406 will run better. you wont get any motor with a 350 holley to turn much past 6500-6700 without the power dropping off bigtime.
