i am hearing that a Lumina engine would fit in my 89. its a 3.1 MPFI i think. i also hear that its an aluminum block and extra sensitive to heat. now if i were to make that swap i'd probably rig my fan to be on always or by a switch controlled by me. also would check my cooling system weekly. but i was wondering if theres a 3.1 chevy block i could put in thats not aluminum? or should i even want that? is 550 a good price? is my transmission gonna co-operate with it?

As my mom alwyas said, "where there's a will, there's a way." If you put your mond to it you can accomplish anything. I dont think the new vin j's would bolt up, buy an older vin t 3.1 might. You will have tp get all the computers and sensors and everything, and probably even the trans axel from the donor car. I think some of those older cav's came with a 3.1 why not look for one from one of those?

and as for the aluminum block.... NO, lumina's have cast blocks and aluminum heads. Which is why there are so many gasket faulures and such. I would just leave the fans alone and let the computer do its job.
