I found out that the 355 I was looking at for my RS has a quadrajet that runs off of a computer from an 87 Monte SS... My question is, would I be better off to try to use this ECM? Or get my harnass modified to accept this carb system?

I want to get rid of my TBI injection definitely. I was just unsure of whether to go with a standard non computer carb or stick with this... Also, can the quadrajet be made to run without a computer??? Thanks!

 

I personally would stick with the computer controlled setup, because it makes decent power and you get better gas mileage. It is harder to tune, so if you want an easy swap that you know will work well go with a non computer carb and dist.

 

Wait, let's take a step back here. You have a TBI car, and are looking at a CC-carb engine. Which ECM are you talking about using? Your harness is not worth modifying - get an ECM-to-engine harness from a '86-'87 CC-carb 3rd gen junker (for the knock sensor, for instance). How much would you actually be getting from this Monte?.

Certainly, non-CC carb is fairly simple - distributor also required - but you'll lose things like TCC lockup. All problems are solveable. But, you don't make a CC carb into a non-CC - just doesn't work that way. You need a non-CC that started out that way. They built non-CC q-jets for a lot longer than CC q-jets, that's for sure, so there are plenty out there. And, non-CC q-jets are available new from Edelbrock.

If you go the CC carb route, do some research to make sure you aren't going to lose something from your '92 that you wish you had back. Same for non-CC carb.
