dont beleive it aods are not quiker my 5 spd will launch like a pro stocker with the right tire and clutch application and maybe break some axles .
the 327s are to much for stock sc it will feel faster but spinning tires is not power its just bad gearing i ran 327s in my 92 5 spd and it felt like a raped ape but in fact it was slower 0-30 than the 273s our sca have massive torque if you gear it to much you run on rpms and not torque the one thing our sc's have .
a 308 would be a perfect match i think
