Wow! You've got my attention. What wouldn't fit with a manual transmission? Was it the clutch linkage or the transmission itself?
The drivers side rear tubes, based on my findings of engine images, blocked the z bar and clutch linkage. The headers were perfect for my app in every way! The forum member was great to work with and he was unsure of the fit as well. At the end of the day he was right on money wise but if I still had the modify the right side, I was taking a huge chance.
My car as with this car has a different engine to have fun with, while saving the concourse correct motor on a stand in the corner. As with any car mine has a history and the engine I’ve got has a storyline too. I’ve got a Tunnel Port that, while too much, was the ultimate wedge motor in 67! The thought was, build the car to “day 2” mods and that’s where I’ve gone. It’s very similar to a few other guys here on the forum too.
Now, a 496 CI, GT40 Dual Plane SK, hydraulic roller, updated TP is of course overkill, you’d kill all advancements by putting small tube headers on it. The engine is detuned and will make 610-620 HP/ TQ based on previous builds from the same builder. So yes, the engine will need it. I just wanted the engine to make street able power, effortlessly. It will probably scare the crap out of me!
I’ve got a local guy that I bought headers from that, well don’t fit, so he owes me the redo. There’s also REF in Arizona that makes custom headers that are said to be perfect but at $1800 or so pricing? Their headers do look VERY nice and don’t scrub! He builds them to order on a actual Mustang front clip with your oil pan, bell housing deminsions too.
I’m still just working on sheet metal so I have time! I’ll post pics of the REF headers.
