I am wondering what can you do to a 3.1, I have been searching and looking but I cannot find anything like what I want. I am wandering what kind of heads can I put on my 1991 3.1 and what Cam is the best if anyone has tried one? Also is it worth the money to switch this stuff if I am going to go to a 400HP 383 in about 4 years? If anyone has any suggestions please let me know. Money is not an object when parts are concerned but I am wanting 200 hp on a N/A engine.

 

I would probably do a couple simple things like a better exhaust and a cold air intake. A good tuneup if the car is in need of one is not a bad idea either.

 

Thanks, I have done most of that, ALso after reading up on this subject I have found that short of just boosting or putting NOS on my car there is really nothing I can do. But I also was wandering how much porting my intake would help, or if I would even notice it?????

 

You wouldn't notice it.

 

Thanks

 

I wonder if you could do the aluminum head swap that some have done to their later model 3.4 engines.
