You could make good power with a 351 stroker and it'll hold together. As far as making it fit, I'm sure it'll fit between the frame rails, but probably have to change the motor mounts or even change to a tubular K member. Just my two cents.

You can do a 302/351 based engine using a '94/'95 K member.

Lots to do though, you'll need a trans that will bolt up, probably a different driveshaft, there will be various fuel and electrical hurdles regardless of if you go carb or efi.

Not a project for the inexperienced or faint of heart. I've read a few of these sort of build threads over the years (a 460 into a New Edge over at mustangforums a few years ago comes to mind) where the end result is a car that's in pieces, all sorts of money invested and still can't get it to run and no end to the project in sight, and then finally just frustrated and sells whatever's left of the car in the hopes of putting toward a car they can actually just drive.

If I can offer an opinion here, given the issues you are already dealing with on this car, I think you might be getting a bit ahead of yourself with talk of a pushrod engine swap. I'd concentrate the efforts on getting what you currently know is wrong straightened out before worrying about this.

For the same price and less headache you can have a Vortech/Procharger setup and be much more reliable same amount of horsepower, and only being a built short block build away from being a very powerful car.

A pushrod swap can be done but as Socal mentioned, be ready....as long as you know what to expect as far the time needed, money, headahces, odds/ends...than go for it.

I am still contemplating swapping a 351 into mine, only because my dad has 2 blocks laying around and enough parts to put one together, but at the end of the day I could get a used PI engine and a used supercharger setup for less money, less headache, and more power.
