Q code. 351-4V
C6 Auto, 3.25 Rear Axle, AC, Power steering.
Thanks for the info. I looked at those on the Summit website and the fitment said the ceramic part # 6915-1HKR does not fit a 71 Mustang and the painted 6915-HKR does fit. That doesn't make sense they are supposed to be the same headers only one is ceramic coated. I am going to check with Hooker directly. You said the last set went in without any massaging, were they the ceramic coated 6915-1HKR headers or the painted 6915HKR?
So I'm curious about the installation of " long tube" headers on a 351C 4V 71 with power steering. Or it it just easier to i stall short tube? How hard is it ? I don't have lift. Is it doable with ramps, jack stands and a pretty full tool box?
My exhaust is new from the manifold back. I realize I'll have to custom fit the connection at the collector. I'm thinking about installing a electric cutout just because.is it worth the money time ? Any other customization needed?
Dead soft aluminum aka Easy-to-Form Pure 1000 Series AluminumThe gaskets are not the old white composite material they used to include, but are more of a manifold gasket style. They didn't last long on the dyno, but they were used on a rusty 30+ year old set of 6921s from my old Cougar, as we needed to "adjust" them with a torch to clear the absorber. I used FelPro gaskets on the actual set and they sealed fine.
Do you think the big difference is because they eliminated the Cats?
I got a quote of 2k from my local mechanic to install the headers on my car and fab the connection at the headers. I will probably just end up doing it myself.
That's what I thought also. I've got some time until it's warm enough in michigan to drive so I'll just do it. We have a welder at work that is really good and does side work so I'll hit him up to weld the connections for me.$2K is a "don't wanna do it" price if I've ever seen one
