Noticeable power gain
Noticeable power gain with excellent sound. Installed them in a 70 Mach1 with a 351C. The drivers side with power steering is a tight fit to say the least, but take your time and the do fit. Passenger side was a breeze. The kit comes with excellent directions. Just follow them- do not skip a step- and you too can install them. Patience is a virtue!

Headers are great. Not so the PS bracket
Installed the headers, and they fit great. However, the power steering bracket required for the installation needs to be redesigned. After installing it and taking it for a test drive, the bracket flexed and made a popping noise. And the steering when turning to the left became more difficult. I had to basically build a new setup for it to work, and would question the long term safety of the bracket itself.

How lucky will you be?
After reading mixed reviews from multiple sites I decided to take the gamble. I was not lucky. I bought these for my 1969 mustang 351c 4 barrel with an AOD and no power
steering. I was actually surprised to see the headers clear the AOD since the car never came with one, but it was close. Headers will need a heat shield to protect starter and transmission. That was where my luck ended. Had to raise engine about half inch, trim a slight amount of metal from the engine mount bracket on drivers side, slightly dent the tubes in a few places, grind about 1/4 inch off the elbow of the pitman arm, and hammer the tube by the pitman arm almost half closed so the car would turn all the way to the left. The chassis of my car has never been altered or damaged either. Motor mounts are new and stock rubber replacements so there is no excuse for this other than poor quality. I would suggest these for a late 60s mustang only if you have no other choice.

Poor fit
Can’t say anything good about the fit of these headers in a 1967 mustang 351 4v with auto transmission.Passenger side was not as bad as drivers side. Driver side was a real mess. Couldn’t get headers past Automatic transmission and the pitman arm. Ended up cutting headers up and rerouted tubes just to get up close. Had to grind motor mounts, pitman arm, stering box, transmission. Lots of denting needed. Now have a pair of Frankenstein Headers that still leak at the heads. Don’t buy these, save yourself a big headache.

Junk for a 70 mustang
This Will not fit a 1970 mustang it hits steering box on driver side and on the passenger side it hit down by the motor mount and you cannot put the idler arm back in because it hit the tube false advertising by saying it fit a mustang if you don’t believe me put it in a mustang
