Hello everyone, I am excited to join this forum! I do not have a mach 1 but I have a mustang that is pretty close. I have a 1970 Fastback with a 351C and an FMX. I have had this car since I was very young because it was originally my mothers car and it was my first car in high school. It was not in perfect shape when I started driving it but I saved enough money to get body work and a paint job my senior year. Then I parked to and bought a 2001 Trans Am that I turned all my attention to and the pony car just sat. But now I am selling my Trans Am and starting to get very intrested in finishing the Mustang up. I am a mechanic by proffesion and I built a fully forged 402 stroker for my Trans Am 2 years ago that makes a little over 500 H.P. But now I want to freshen up the the cleveland and get drivabilty and reliability to this car. So I guess I have a few questions if any of you would be willing to help. My first question is how rare is my car? I still have never seen another 70 fastback in my area (colorado Springs). Next question is where can I find cleveland parts? Been having a hard time finding them? And my last question is in what direction should I go to make and little more power out of this motor? It is a 2 barrel carb on this car that is the original carb. How well do the clevelands take to a slightly bigger camshaft? On a closing note. The motor was refreshed by my grandfather in the early 80's I.E. new bearings, rings, headgaskets. but the car only has 91,000 miles on it. Thanks in advance for any help.
Welcome to the club - really glad to have you here!
Nice history on your car, definitely a keeper.
How rare is it? I was looking for production numbers (they are here somewhere) but couldn't come up with them in short order. I do not know how many fastbacks were produced in comparison to Mach 1's for 1970. That information is here somewhere. As you can see on the 69-70 Title page the numbers of Mach 1's in 69 was 72,458 and 40,970 for 1970. I would imagine that that number would be reflected in the fastbacks as well i.e. fewer 1970's than 1969's. Again although the production numbers may be smaller and therefore rarer that is not the only consideration of price. Personal desire being the greater factor.
As for the 351 Cleveland and power! The 351 C is know as one of the best motor foundations on which to build huge power. There are a lot of articles here on engine tech, pro's and con's of various combinations etc. Dive in and check it all out. Basically, stroke it and cam it and hold on. You'll be pleased and impressed.
To start with though it doesn't need that much. A good 4 barrel intake manifold and appropriate carb. Research a cam (these guys are specialist and they are close to you in Englewood: http://www.camresearchcorp.com/) and you will wake up that Cleveland.
Thank you to eveyone for the great welcome, I am really excited to get back into this car. I dont know why I ever stopped HAHA. My mother actually ran a report from MartiAutoWorks about 2 years ago and she thought I had seen it. Found out alot about it. I was looking around on stang-aholics is this a good website to buy from? Also with the FMX is it going to handle the extra wake up form a 4 Barrel and I cam? Dont know to much about these ford trannies. Thanks alot guys!
Welcome! Hey, I'm also in Colorado Springs. I would highly recommend joining the local Mustang club, the Rocky Mountain Mustangers. Here's a link to the web site:
I went to a meeting for the first time last Saturday. They are a very nice bunch of people. My friend and neighbor has been a member since the 1980's. I'm currently looking for a project Mustang. Nice to see you already have yours!
As for your Cleveland, indeed, you could really wake it up with a 4-barrel and a decent cam. There are many options and many opinions out there. I built a 351 Windsor some years ago. I had very good results running an Edelbrock Performer intake and Performer plus camshaft. This combination will not only significantly increase power, it will keep your car very driveable and an very streetable. Edelbrock now has a "Performer RPM" series which would be an even better option. You can certainly squeeze more ponies from Cleveland with a more aggressive cam and intake. But you would give up driveability. Since you're running an automatic, you might also have some problems with idling.
I would also recommend Edelbrock's carburetor. It's simple and reliable. And it's also very easy to work on. You can re-jet it while it's still bolted to the engine. This comes in very handy while you're trying to dial in the right air/fuel mixture at our altitude.
Take care and let us know how we can continue to help you.
The FMX should be up to the power addition after all Ford did put them behind the Cleveland 4V motor from the factory. I ran without incident in my 1970 Torino 4V Cleveland that was able to pull the front tires.
Most are keen on upgrading to the C6 but that does involve some other part swaping. The FMX like the Cleveland was left behind by Ford and aftermarket companies through the years in favour of the C4 and C6. Parts are out there though.
Welcome to the site Thunderin351! As I keep saying owning a Mach 1 is not a requirement to be here! Thanks for signing up, the more the merrier!
Nice to see the site moderators are on the ball good job guys!
Alright guys I am pretty much set on the edelbrock RPM air gap Intake but I dont know which carb to do. Was thinking a 600 cfm but not for sure if I wan to run an edelbrock carb. A holley should bolt on this manifold also shouldnt it? If so any recommendations would br great.
KEWL car enjoy the site and welcome from Iowa.
