Well the plan WAS to buy a 87 350 for my 85 blazer and put a TPI/TBI system on it. I just got back from the Chevy dealer and as it turns out I can't do this if I want a warranty!! It has to be original application to have the warranty. And I don't want a Carb any more. My only other option is to buy a RAM JET 350 for $5265!!! with a 12 month warranty. Question is how good is this RAM JET 350? Is it worth it? Is there any other options? I really don't want to keep the Carb.
