Ok. As the title says, I want a new engine in my FORMULA. I'm seriously thinking about an older Caddy engine. When I searched for an older Caddy, with a 4.9, I came up with the engine, I think. It is a 500 ci BB. It was in the Caddys in the late 70s early 80s and I can get into one really cheap! Whats more, it is in a front wheel drive car, so my question is this-

If I have the frame from the caddy welded onto the subframe of a fiero, is their any reason it should not be a direct subframe exchange?

I assume you're talking about an elderly Eldorado. While those were front-drive, they didn't mount the engine transversely. To fit that into a Fiero, you'd need to stretch the frame - that drivetrain is HUGE.

That engine can be put in a Fiero,but it would have to be mounted longitudinally.See what Cardealer did with a small block in his car.The only thing is the Caddy is a torque monster but doesn't have much horsepower.

There is a pic of a 500 Caddy powered Fiero on the forum somewhere. I think it was an Indy.

And I dont think you have to stretch the chassis, but you would lose your trunk.

Check out Fieroaddiction.com for info on longitudinal mounting.
