front exit headers

Post  BigRigTech on Mon 19 Dec - 11:00

I want to get the front of my car down some so I would like to build a set of front exit headers as my hooker 460 swap headers hang down pretty low now. I was going to mod my super comps but after a good look at them on the weekend I think I'll be further ahead to start from scratch. Does anyone know a good spot to buy a long tube header fab kit for a BBF? I have A429 heads, I need at least 2" primaries and 3.5" collectors?

Check on summit they have a number of kits avaliable, you'll have to hack them up obviously but you'll get flanges collectors and tube.

Speedway Motors has a budget-minded kit....comes with flanges, primaries, collectors, gaskets and bolts...all for about $150.

X2 I used that kit http://www.speedwaymotors.com/429-460-Big-Block-Ford-Header-Kit,37279.html  to build my 1st set with when I went to fender exit I bought a kit from summit with just tubes and collectors I went 2 1/8 into 4'' collectors and reused the flanges from speedway

Thanks guys I'll check those places out. It was suggested on YB to buy a BBC header kit and get some BBF flanges. That's an option I hadn't considered.

That's what I was thinking you might have to do if you cannot find a 429/460 Ford specific kit.
Tubing and collectors are generic to any motor, you'll just need Ford specific flanges.

Ok thanks for the help, I think I'll get the speedway kit and maybe the $89 summit kit too and that should give me lots to work with. Very Happy

I had 1 tube left over from mine but wouldn't hurt to get a couple extra j bends just in case you need them

Front exit stuff is usually easier to build, too...Fewer tight spots and tricky bends, much easier installation. With a little planning the Speedway kit will do the whole deal.

I need to get rid of the mess you can see in the pic before I can drop the nose of the car. I bought some 12" springs to drop the nose 1-2".

I'm no expert by any means but it seems you need to drop the car at both ends

The rear suspension is set up for 275 Pro drag radials. It separates the body about 1" from the tire from the hit out. The front end is carried up like this through the pass but it sits a fair bit lower when it's idle. Ideally I'm told my rear pinion angle should be -3* where as right now it's +1*. I have to level my engine out to get the driveline angles better so I can try to get the pinion in the negative. I just started working on that last weekend. The rear springs are Team Z's. The biggest thing I need to get now is a good pair of rear DA shocks. I'm hoping to get some used/truned AFCO's from Menscer's at some point. It's a work in progress LOL
