My dream car would go as follows:
355 stroker (302 block)
EFI all the hi-flow stuff: Edelbrock victor extrude honed, all the other intake stuff, AFR 200 heads matched to the intake and exhaust, High Flow turbo cam
Twin Turbo system
Factory type drag suspension and full chassis stiffening including welding subframes/cage together into the car....but making it look 100% stock from a glance.
There would be alot of other stuff like fuel system, cooling system, etc. etc. etc. that i would have to install but this is the general engine stuff.
I would have a 6 speed tranny (probably wouldn't live with the engine, but oh well) and a 9" Rear with mini tubs...
....exterior completely stock save for steel wheels enlarged to 15" and 15x10" in back with stock dog dish hubcaps.
.....all in a '79-'83 Ford Fairmont 4 door or wagon
