i have a 9.7-1 bbc 572 in 22 ft. stryker and i want to up the power a bit and i was wondering how much compression can i run if i mix 100 low lead av gas, 50-50 with 93 octane? I have dart 345 aluminum heads, roller cam, pro systems 1050 dominator on merlin x intake. Solid roller cam 114 lobe sep, 268-276 duration @ .050, .704 .704, 4/7 swap comp cams. Dynoed at 720 hp.
How much more horsepower would be made going from 9.7-1 to 11.5-1? Would you believe it will run 108 mph @ 6700 rpms like it is and im still not satisfied. What do you think?
