I have a 1987 cutlass supreme,which has the regular gauges. an i have seen the 442s with the floor shifters an all that good stuff with a diff gauge setup. so can you put that in a regular cutlass supreme?

 

Sure can!

There is a procedure here: Rallye Pac Conversion - G-body

But there is a better one here:

Also, visit Oldsgmail.com and look through the member co-founder's pages.
There is a slew of valuable info there for your G-body. Tom Lentz, especially.
If you still have questions, feel free to ask me. I did this swap in my 86 CS and had no issues. Great cars, just a bit low on power...

 

Nothing a good 350 or 403 won't fix!

 

thank you very much!An yea 170-180 hp is not so nice, but there is a lot you could do to get it were you want it.
