They are non-interferance. Not much out there for performance upgrades enginewise. Transmission though....there are a few options. Check out any of the turbo Dodge forums (of the 2.2 and 2.5 liter varieties).
EDIT- they use the same transmissions but with different bellhousing patterns.

I heard there is alot that can be done to the engine, such as the 87-88 TB and plenum, timing advance, PEMs, and other little things I read about.

I'd rather spend money on the Bonne though! But heh, you only bought it for $50, I guess it wouldn't hurt to upgrade some things. lol

I just got an awesome idea, I wonder how hard it'd be to drop in one of those turbo SRT-4 motors. That'd make a sick ride . Just a thought.

It needs a ford windsor imo. :o

Cleaned the inside today, cleans up pretty nice for 250k.

I'm officially jealous.

a running car for $50? thats a better deal than my lumina

Yup, I was good friends with him, so he gave me the deal. Pretty much it was "Buy it or I am sending it to the scrapyard." I said, "I'll take it!"

wow, TWO running cars? is this a record for you? :P

congrats on the sweet deal
