I have a 1980 buick regal. I got for free with a cracked block. what other types of engine can i put in it with out doing any modifications on the car. thanks for the help.

 

[78 monte]

I had an 85 regal w/ a 350/TH350 in it.
All ya gotta do is move the frame mounts and move the tranny crossmember and drop it in.Then get some 78-87 montecarlo headers or manifolds and crossover off a monte and go for it.

If you want to stay with a V-6 you can go with a 4.1 or you can drop a 350 Buick right in. The 350 will go in without having to change a thing.
