  1. Hi everyone. I'm working on my 69 Mach 1 which was a factory 4 speed manual transmission car with a 390. Before I bought the vehicle, the engine and transmission plus threw shifter had been removed and an automatic shifter had been installed. The previous owner was running a 351w with an automatic. Not sure if it was a C4 or C6.  The clutch pedal had been left  in the car, and secured up out of the way. I want to use a C6 automatic transmission, because that's what I have available. I also am installing power brakes with a new power brake pedal. Will I need to remove the clutch assembly in order to clear the brake pedal?


  2. Thank you everyone for your input. To answer barnett468's questions, I only intend to drive the car mildly and at regular city/highway cruising speeds and I will not be racing it or driving very aggressively. At least not yet LOL. The reason I want to go big on the tires is to fill the wheel wells as much as possible, and given that my rims are only 14 inch diameter, I'll need large tires to make that happen.  The Cooper Cobras sound good, and are more in my budget.  Can I do 235/75-14 all around? I believe that would be the widest and tallest, right? Am I correct that 235/75 is taller than 235/60? Any clearance issues with 235/75-14? Will those tires fit the 14x7 rims?


  3. My 69 Mach was originally equipped with the S-code 390 and 4 speed. It now has a 351w from an 83 Bronco, with a C6 auto. Trying to install a set of 6901 Hooker headers, they fit fine after raising the engine up a few inches to maneuver them into place. However after lowering the engine back into the mounts, the headers seem to be up too high at the tail end, such that I can't imagine there's enough clearance for the h-pipe (which I don't have yet). Anything obvious that I'm doing wrong?


  4. Bought a $45 load leveler sling from Pep Boys on Saturday and put the engine into the car with transmission attached. Did it by myself in an hour. I bolted the sling brackets to the front and rear sides of the heads (standard cast iron heads, not aluminum). The sling worked nicely. You can angle it up & down in order to slide the tranny into the tunnel.


  5. I am working on a 69 Mach I and have a 351W with C6 ready to install. I have bolted the trans to the engine and am wondering where to attach the hoist hook. I have seen it done several ways, but wanted to know the "best" way to pick it up. Can I run some bolts into the intake manifold? Do I need a special sling or brackets? Thanks for your input.


  6. I bought a 69 S-code 4-speed Mach 1 in 1999 and it was in rough condition, with the 390 and trans missing. It had new floors, installed poorly, and had a decent non-original color clearcoat red paint job over top of poor body work. Interior was rough but complete and liveable. I had it appraised by a pro and he listed it at $8, 500. I think that was a little bit optimistic.
