This will probably raise some eyebrows. If two 1973 duster's were the same weight, had the same size tires and tire pressure, both had 3.23 gears, a 904 transmission with a stock rebuild, stock stall speed converter, one has a 340 the other a 360 but they both are rebuilt to the 340 specifications. Both have the factory 1973 340 exhaust manifolds, factory intake and carb that was available on a 1973 340 duster and 2 1/2" exhaust system, would the 360 out perform the 340?
