  1. I always tell people the heads are the key to making power. Since the Cleveland heads are pretty good to start with, I woukd say the best bang for you buck would be a set of gears. With the automatic, a "lower" gear ratio (3.25 or 3.5:1) would be most practical. Of course that depends on your intended use. I woukd go with 3.25:1 since I drive on the freeway most of the time. After gears, I would consider a full exhaust. Mid-length headers, 3 1/2" pipe and a flow through muffler (my preference). After that, I woukd go with a performance dual plane intake manifold and a 4bbl carb. I like Deamon and Holley. 600-650cfm is all most people really need for a street 351. If you want to go any farther you can always have your heads rebuild (cleaned up on the inside) and a healthy cam. I like a hydraulic roller 224/230 @ .050
  2. I converted my '68 coupe from a 302/C-4 to a 393w with a Tremec TKO-600 with a kit from Modern Driveline. The kit was very reasonable and easy to install. Now I plan to do the same swap on my '73 Mach-1
  3. It is the 4v heads. As for the block. I was told it was the 4 bolt main. I believe I even have a picture of the engine as it was being rebuilt. I forgot to mention it was rebuilt with the hydraulic roller conversion.
  4. I have a '73 Mach-1 with a 351c 4v. I prefer to trade but will sell if the price is right. The 351 has been rebuilt with forged pistpms, hydraulic roller cam, Edelbrock single plane intake and a Holly 4bbl double pumper. The C-6 was also rebuilt. I also have a set of long tube headers if you want them. I have another motor for this car but am saving up for a Tremec TKO-500 or 600. I prefer to trade the motor/trans for the TKO but will sell if the price is right.
  5. I'm not sure about this car specifically. But from what I have seen online, a 17x8 wheel with a 245/45-17 would have a backspace of 4.5 inches. For a rear wheel of 17x9.5 with a 275/40-17, the back space is anywhere from 5-5.5. At least I'm hoping. I'm planning for a 17x8 and 17x9.5 seet of Vintage 45's for mine.
  6. I do appreciate everyones input. That sounds like good advice. I do understand how the springs work, it's just that I am use to the SN95 cars with coil overs. I actually have the 600#/165# springs on my '68 coupe. And that's a 393w with aluminum heads, intake and a TKO-600. The Mach 1 has a 4v Cleveland and I assume the car is quite a bit heavier than my 68. As for suspension parts, is Global West better than Total Control?
  7. I have good luck with both a Holly and a Deamon. I have heard a lot of people have had issues with the Deamon but I love mine. There is also the Edelbrock (old Carter AFB) but everyone I have spoken with said they tend to stumble a bit at part throttle. But I have never used one.
  8. For my '68 coupe and my '73 Mach 1, I bought kits from Glenn's Performance. They sell kits as well as individual pieces.
  9. Hello everyone. I have just recently purchased a '73 Mach-1 that is in dire need of upgrades. I will post pictures soon. Anyway, In addition to the fron tires/wheels being too skinny and the rear wheels aren't too wide (15x10) but have the wrong offset and stick out from the fendes 3-4 inches. As for the suspension it is shot. It bottoms out in the front and the rear when going over speed bumps. What I would like, is a car that handles well but too bone-jarring. Following is a list of items I have been looking at and was wondering what everyone thought: -Upper/Lower control arms from Total Control -Strut Rods from Total Control -1 1/8 front sway bar -3/4 rear sway bar -600# coil springs from Maier Racing -165# leaf springs from Maier Racing -Koni shocks -17x8 Vintage 45 wheels (front) with 4.5" BS (245/45-17) -17x9.5 Vintage 45 wheels (front) with 5.5" BS (275/40-17) Of course this will not be cheap, but I would like to know if I am on the right track. I appreciate it..
  10. Very nice. I jusy picked up a '73 Mach-1. Not nearly as nice. Pretty ghetto actually. The front tires are too skinny, the rears are way too wide they put aftermarket switches for everything. I wish my car was half as nice as yours..
