Title: header ground clearance
Post by: loudnlow87 on May 07, 2008, 09:01:25 pm: so ive got the front clip off the truck right now and while i do im doing some other stuff to it. finally put on a set of headers ive had for years. my brother originally bought em for an 84 cutlass he was gonna drop a 400 into, didnt use em and gave em to me. the guy he bought em off of at a swap meet thinks theyre for a 70s g-body. one tube on the passenger side is 1/8th inch from the frame rail but my main concern is how low they hang, about 5-6 inches below the rocker, and they angle toward the ground maybe 15-20* down.
how do other headers or the ones designed for these trucks fit?

"The headers are Hedman's for 67-69 camaros/ 70-72 chevelles. They fit awesome( didn't even have to pull the spark plugs to install) and they don't hang low like full-lengths if you plan on slammin' your truck. "

Sounds pretty good to me. I have headers on my truck, although I have no idea what make/model they are. They fit fine but get pretty close to the passenger frame rail.

Post by: team39763 on May 16, 2008, 03:24:42 pm: My full-length hedmans(for the truck) weren't that bad. My truck was lowered 2" in front and I didn't have any ground clearance issues.

Post by: loudnlow87 on May 16, 2008, 06:28:26 pm: how far under the frame did they hang? my trucks already lowered 3" and is gonna be at least another 3" if not bagged. my stock crossover pipe scraped on steep driveways.
