Hello my name is John I'm new to the forums. I recently bought a 91 240 for 1900. The guy I bought it from had replaced the engine with one from a 95 version and also added a few bolt on such as short ram and headers. He also installed a short throw and did a battery relocation. Heres the thing I took the test drive and it ran fine other that I could feel it needed a tune up. The guy also told me he has never had any problems out of it. So I was like I'll take it. Well, it ran well for a about two weeks and then trouble. I discovered that the car had a short some where in it plus the alternater was bad. Also it developed a slight timing problem. And I can't figure if the car was worth the work I got to do to it. Just thought I'd ask and see what you guys thought.
