    Default 1987 Silverado 350 TBI header helppp!

    Hey I am in a pinch here, I need some headers for my 87 so here is the problem. I have the year that they switched to the TBI intake but did not switch the body style yet. So what my question is... is do i go with the 88-95 headers because its the Throttle body motor or do i go with the 66-87 which i assume is the carb motor headers?!? Ahh I dont want to order and have them wrong because i am thinking about getting them off ebay but i think the 66-87 headers are for the carb 350's but im not sure. Ha any help would be great. Thanks in advance. And i will get pics up as soon as possiable!

    I'm going to take a stab at this. I'm guessing the 67-87 headers would fit in the engine bay better. IIRC the exhaust ports are the same shape and size for the carbed and TBI motors. If I'm wrong forgive me but that's my best knowledge on the subject.

    The TBI or Carb doesn't change what headers fit the 73-87 truck.
