    What is the best rear axle ratio for our cars?

    I've run both a 2.79:1 and a 3.5:1 truetrac in my Mach 1. I do a lot of highway driving, so the 2.79 is actually my preference eof the 2. I also built my 351c to have a pretty broad torque curve so it has plenty for me off the line for street driving. The 3.5 was better off the line and more...

    Duraspark II with ram air debacle

    I ran into the size issue with a Cardone dizzy and the small female cap - initially I just dremeled out a very thin layer around the inside of the plastic cap to get it to fit. A year or so later, I needed to replace the older cap and the replacement caps fit perfectly, so there must be some...

    Aftermarket Steering Wheel blues

    That wheel was used on some mustang II models (74-78). I had a black 1978 4-speed fastback with that style wheel and slotted rims. Wish I had it back.

    General information on Car lifts?

    For jobs like the one pictured, I would agree, the 2 post lift is better. However, 4 post lifts are extremely useful, more than often perceived. I've used my 4-post lift for routine maintenance, engine & transmission swaps, rear end replacement, exhaust and brake work on multiple vehicles, and...

    I am needing a tachometer gauge mounted

    Rocketman can convert your clock to look like a factory tach. It's wired differently, but its only 3 connections. You do NOT have to butcher any factory wiring, and cosmetically you can't tell it's a conversion. You will want a new lens for the entire cluster (it's one piece and that allows...

    TMI sail panels

    The resin is a way to go, but seems like more work than it's worth for a simple sail panel replacement & mounting fix. I just went through this, wish I had taken pictures. In my case, I broke the pocket away from the pressboard/paper tabs while test fitting the sail panels to ensure placement...

    1973 Mach 1 FB Marketplace barn find

    Hemikiller is correct (as usual). I have a 71 F-code that originally came with a 302/C4 drivetrain. The 3F05F vin code is exactly as he describes, and was a 1971 option. My original engine was long gone when I found the car, and now replaced with a 351C, but my research on the car upholds the...

    Gas Smell

    Wow... I've always had reasonably good experience with WCC - what condition/grade did they claim it was in? Looks like this should have been down in the D, E or F area... probably closer to F. If this was supposed to be anything close to driver quality, I would tell them they need to make it...

    Looking for 351 Cooling Improvements.

    How is your ignition timing set up? Insufficient advance can cause hot temps at idle.

    New to the group

    That's a really sharp car, but admit I'm biased toward black Mach 1s...(see below) I really like the 73 side stripes, even more than the 71/72 ones, partly why I never added them to mine.

    Carburetor heat shield

    I hear it can help, but was just offering a cheap solution - the combo of a heat shield and return line are easy and relatively cheap.

    Carburetor heat shield

    It may not be pre-pump vapor lock. temps in the engine bay can be pretty hot, and fuel can boil off between pump and carb with the same result. When I had my old hot-rod vette, I fought issues with gas boiling between the mechanical pump and carb. Newer fuels are more prone to heat-related...

    351 Cleveland Overheating Issued

    Fan placement does matter, but doubt it'll make or break you as far as running too hot. I've always been told the fan should be just inside the opening to get the most effective draw of air through the radiator. Another thought might be timing - retarded timing or very low initial timing can...

    F-ing HOA issue!

    That car is most certainly NOT an eyesore. I'd drive it in a heartbeat. I love the idea too - but I'd be inclined to challenge them. Do you have a copy of your HOA rules? Usually the intention is to go after cars that are visibly broken down and/or obviously not drivable. That car is nowhere...

    Need some ideas

    Maybe a dumb question, but is the choke coming off/operating correctly as it warms up?

    Upgraded Carb

    Ain't that the truth - I had the opportunity to work with 3 different QF carbs last summer, and every one out of the box was an absolute mess - every possible adjustment was wrong or off somehow, and one leaked from between the base plate and main body so bad we just it back.

    Steering column adjustment?

    I had this alignment issue. The ability to adjust is limited, but I got mine centered to a visually acceptable left-to-right position by loosening all 4 of the bolts pictures as well as the ones that mount the column base into the firewall. The two studs on the topmost part of the brace act as...
