Ford vs Chevy Build-up

Tony Corley · 03-28-2015, 08:52 PM

The steering swap didn't affect it. Will they fit with the shaft between the tubes? With my Kooks, they actually do have the shaft running between them, but they come apart to make it easy. I have never ran the Mac longtubes, but never heard of them having serious fitment issues.
Make sure that whatever you get specifies that they work with an automatic. Not all Fox headers will.

EDIT. What motor mounts are those? Do you still have the factory mounts laying around? If so, double check the heights, and the forward/backward postition between the 2. Some aftermarket mounts move the engine, and can cause all kinds of header fitment issues.

Guess I will be removing the steering shaft...really looking forward to that. What part number Kooks are you using Tony?

The 2 sets of Hedman headers I have had on my car, the steering shaft has to be removed. I also run the exact same engine mounts.

The steering shaft should not be that big of a deal to remove and reinstall. Your getting really close to having it running!

Rich, I kinda skimmed back through and didn't see much detail on the engine, unless I missed it.
What did you do for pistons? Ring combo? Cylinder heads? Camshaft?

Thanks

Brian is trying to send me a link to the Flowtech headers he uses...individual tubes like the Kooks.

Mark - I used a CompCam Stocker grind 246/252 @108. Cheap approved SpeedPro pistons with an oddball TotalSeal ring package. Heads were refreshed with new valves, beehive springs and pedestal mount roller rockers. Did the best I could with oil control.

I second looking at those motor mounts what brand are they? not to many people make solid mounts for the foxbodys and some have the engine in a different location then stock. I believe the rule book says engine placement in the stock location. my headers are kinda touch if the motor is not level in the car, big slots in the subframe for the motor mounts. I use pacesetter on my car under $300 for them, my merge collectors are more money then the headers.

Problem solved... http://www.summitracing.com/parts/bi.../model/mustang Slip-fit tubes will make my life easier...all I need do is cut the flanges. I don't recall the brand of solid mounts, but yes the engine is still in the factory location front/back - up/down.

I'm not inclined to mess with that shaft again...it was a pain when I put the manual rack in.
