I have another question for you guys. I'm trying to find a stock replacement for my 86 blazer. I contacted edelbrock about my carb, part number 17085226, They said it was computer controlled and that they didn't have anything. I have two questions. One, how isthe carb computer controlled, and is there any other carb out there that will fit my blazer that doesn't cost $600 bucks. Thanks for the insite.
