That is one good looking Cutlass. My 88 Cutlass is mostly orginal with 198000 miiles on it. I got the car new. Pictures are in the technical and reference forum. A 455 would require some cutting...A/C or not. A guy I work with has done it in a 85 Cutlass. I am happy with the mods I have done with mine, A different cam. different gear and Hypertech performance chip. Good luck and keep us up to date on what you are doing

 

Sorry to report I haven't done much with the '86, YET, other than drive it around the neighborhood every week or two. Can't wait to hit up a few shows this summer to keep learning about these cars. I still get on here at least once a week if not every other day.

 

I know this is a little late, but if you are still wondering what to do with the engine i would throw a buick grand national engine in there.

 

Find a good running low mile Olds 403 engine. Regasket the engine, change out the plastic timing chain gears & chain with new ones & then add a mild cam & new lifters. Reinstall your existing intake manifold & carb. Done.

This can be accomplished for under $1000 & your time. This will be the most bang for your buck. Your 442 will run the way it should have when new.

 

Good advice.....I agree that would be the most cost effective way to upgrade his Olds...
