I'm building a .030 429 that has TRW flat tops and is balanced and has a set of stock valve size thunderjet heads that have been port matched and the bowls blended and a RPM intake that is gasket matched as well and will have a 850 E-85 carb, the cam is a XR280R-10 soild roller its .657/.664 lift and 242/248@.050 what I wanna know is how much HP will it make? and then I'm building a .030 460 with TRW forged light weight pistons and stock rods and its all balanced as well, then I'm putting all the 429 stuff onto the 460 like the heads, intake, cam, lifters ect, then how much more HP will it make? thanks for any input, Butterbean
