Summit Big Block headers - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Has anyone used the summit brand big block headers for our trucks? How low do they hang past the frame? Im going to get a set tomorrow to convert to use on my LS1 and dont want them to drag the ground.

ok i'll answer my own question. These headers are NOT made for lowered Blazers. They hang about 8 inches below the frame (not good when you only have 9). They are also going to require A LOT of fabrication for an LS1. In other words if you have a lifted big block truck they would probably be a good value, but not so good for a lowered small block truck.

I have these headers on my big block, it's lowered, I'm happy

I did have to have them modified on the left side I believe it was, for fitting issues. 402BB/AC/Auto truck
