72 350 Rocket for Chevy

[drec02]

First off this is one of the coolest car sites I have been to, glad to be included. I have a 1972 350 Rocket from a Cutlass with cast 7sub-script A heads I have modified it with an Edelbrock Performer RPM: cam, lifters, valve springs and intake. Comp Cams 350 Magnum roller rockers and pushrods w/guideplates. An Edelbrock 750cfm carb, a set of Flowtech Headers, a 2600 stall converter mounted to a TH400 transmission with a B&M transpak shift kit. Hope this combo gives me the HP and torque I'm begging for! The catch is....this motor is for a 1974 4dr Chevrolet Impala that orginally came with a sbc 400 and a turbo 400 trans. Would anyone happen to know what modifications will have to be done?
