hey guys thanks for all your responses, ive decided to keep my 283 and rebuild it, ive been told be a V8 performance shop that i cannot stroke the 283 but i can put 60 tho oversize pistons to increase the displacement to just over 300 ci. Im going to disassemble my motor and freshin it up with some new pistons/rings and bearings, plane the head, high lift cam and some good extractors, this should do the job nicely, the engine is in a 1991 Mazda Luce so altho its a big car it wouldnt be as heavy as an impaler or what ever the 283 came from.
