I installed a set of the Clipster mid length headers on my car last week and so far i have found no problems or drawbacks. The mid length clipster allows you to drop the frontend of the car and not scape your headers on every speed bump. They are of very high quality with a nice ceramic coating and a thick flange with good sealing. I had read that mid-length headers would effect low end torque, i cannot tell the difference by seat of the pants testing. The best part, $250.00 and they clear angle plug heads nicely. Before someone askes, yes they fit around the steering box and have plenty of starter clearance on my 73 Nova. I give them a 10 for quality and function! graemlins/thumbsup.gif

will they clear the clutch linkage on a manual trans car?
what engine mounting setup are you using? a 327 and 307 uses different frame and engine mounts than a 302 or 350, and the engine sits farther back with 350 mounts, which will affect fitment with a differnet combo.

It is my understanding that they will not clear manual transmissions. I am using the 307 mounts with the clamshell type motor mounts.
