!968 Mustang Coupe PLZ HELP?
You must have a lot of money. Just to cut fit and weld new cross members and suspension, not to mention cut the firewall because the ignition set up is all to the rear of the motor. Then you need a transmission to fit along with new trans cross member drive shaft, u joints, exhaust that will have to be total custom. Then you will need 4 wheels disks and new brake lines suspension front and rear. Why don't you buy a Camaro instead.
The Mustang has so many hipo bolt ins from 289, 302, Boss 302, 5.0, 351C, 390, 427, 428SCJ, their is also an aluminum block 460 that is 500hp. These will bolt straight in and fit into the engine bay.
I do find Mustangs boring and a dime a dozen but I hate seeing Fords with Chevy's in them. As for the Holden in a Toyota that's great.
I added a few websites with some great options that have over 500hp Ford bolt ins.
