is it possible to obtain 450hp from a 396. if it's possible can you guys give me some ideas
thanks

the link shows the print out from my first dyno pull on last years motor. It's rear wheel horsepower. The motor is a 396 +.60 a 408, cleaned up merlin oval port heads, merlin dual plane intake, holley 750 vac sec, hooker super comps 2"x 31/2" collectors, Comp Cams 294S magnum cam, I probably should have gone with the 284s. Add on the 18 percent difference and it is right arround 500 HP. http://www.chevelles.com/showroom/ricks_67/firstdynorun.JPG
