About how low do they hang below the frame I know not ever car willl be the same but a ruff estimate would work. My car has already been lowered but im not going any lower.
"Standard" trifive headers all are designed to clear the stock rear mounts that attach at to the sides of the bellhousing. This puts the bottom of the header about 2" below the front part of the frame right before it curves upwards. This is usually the lowest point to the ground as well. If your car is stock.. no problem... BUT if you are using 2" dropped spindles (depending on the aspect ratio of your front tire as well) the (standard) headers will only be about 3" off the ground. I know this because when I first built my car, I had 2" dropped spindles and standard Hooker Super Comp's... that were low enough to drag on the ground if going on a bumpy freeway at high speeds with two guys in the front seat. Forget speed bumps! Now I have the 2" dropped spindles and 1" lowered springs... ain't no way I can run the standard type header now. My frame is only about 4.5" off the ground. So, I would recommend either 3/4 length Patriot style, or a full length for "lowered cars." If you go with the full length, you will need to remove those rear trans mounts and go with a crossmember at the transmission tail shaft.
I have already removed my frame horns and have 2" drop springs. Can someone link me to some headers for lowered cars? I might just pick a set up of the flowtechs from oreilys and see how they are I work at a shop so taking them back is no problem if they hang to low. Also will flowtechs work the angle plug heads , 3/4 forward side mounts?
Based on glowing comments from a Chevytalk member several years ago, I bought the Flowtechs for my '55. They fit well except there's no way the stock clutch linkage will work - maybe ok for a hydraulic clutch setup, and certainly fine if you're running an automatic. Summit took 'em back, no problem. Ended up with the Patriot 8025 (perfect for lowered cars).
Whoops, I just looked at your ebay link and those are not the same Flowtech's I tried. Those look like they would clear the stock clutch setup just fine.
