72 mustang question
 

I have a 72 Mustang Fastback. It's a Q code Cobra Jet car but the 351 is toast.I have a 302 and C4 that I could put in the car. what class would it run in? Would it be good to build this car?

Re: 72 mustang question
 

That probably isn't going to work. The 302 is a 2BBL NHRA rated at 143 HP. The weight break is 21.43 lb/HP but that will put you in U/SA at the 20 lb/HP category. In order to make the lower end of the class you would have to weigh 3030 lbs. It would be very hard to get a 72 Fastback that light.

It is interesting that the 302 had its HP refactored in August 2013. I don't know what it was previously or why it was changed. It was probably a competitor request to lower the HP, but maybe someone is actually running that combo. I have never seen one.

Keep in mind that there is virtually no difference between the 71 and 72 so you could run it as a 71 Fastback or Mach1 and look at those engine combinations too.

If you want to run it as a '71 429CJ/SCJ, let me know. I have everything you need.....

Re: 72 mustang question
 

Go ahead and get that Cleveland engine built to run stock in e or f we need more Cleveland stocker on the west coast I believe it's only 2 that I know of.If you need some help let me know.

Re: 72 mustang question
 

Sooner, I'll throw my hat in the Cleveland ring, except it's not "under" yet & it's the 2bbl. version. Since Youngblood went to the dark side, I can't think of any other 351C's up here in D6. Are the 2 you speak of in D7 ?

Re: 72 mustang question
 

I was hoping for a budget build. Isnt a cleveland big bucks to build? At least i have the carb and intake already.

Re: 72 mustang question
 

Me and Steve in d-7 and there is another but he hasn't bought it out as of yet.

Re: 72 mustang question
 

So what exactly is the definition of "toast"? Is it completely blown up, like a rod through the block or does it just need a full rebuild? Does it have the correct heads, intake and carb?

Re: 72 mustang question
 

Might be a little over stated. The car sat for 15 years before I got it. It's .030 over and 2 of the cyl's were rusted tight. I had to gently beat the pistons out. LOL. It might clean up O/S but not sure yet. Heads , intake, and carb are all 72. It's also a 2 bolt main block.
Looks like the reason it was parked is 2 of the cam lobes are round...LOL

Re: 72 mustang question
 

Well take that pup over to the machine shop and find out if it can be saved.Not all of the E and F cars on the west coast are super fast.Plus you don't have to have a aluminum intake you can still use a square bore intake and QF holley it will just be heavy.

Re: 72 mustang question
 

There is also the D1ZE-BB intake that can be used with the Motorcraft spreadbore. It measure's big. I ran one in bracket's & it did OK but not sure how it would work on a stocker.

Re: 72 mustang question
 

Doesn't the stock racer in Arkansas with the 73 have to run the motorcraft carb and that car runs well under in G and H.

Re: 72 mustang question
 

I'm at work but I do believe that's The carb and intake i have. It is a spreadbore for sure.

Re: 72 mustang question
 

That Is Verne Buchanan. The only intake & carb in the guide are:

D3ZE-AA, & 11 – 1563x1960/1250xAV

Re: 72 mustang question
 

Yea that's the one,Robbieracer you should try to run this combo low compression dish piston,open chamber AA heads ,.481,.490 canshaft and you already have the carb and intake.may have get another hood I don't think you can run ram air with this one.

Re: 72 mustang question
 

I have never built a Cleveland motor before so this is new to me. What class would this run in and why the change in hood? Would the car still run as a 72? Isnt the 4v 'Q' code car a Cobra Jet and wouldnt that be a ram air hood? Sorry if the questions seam stupid.
I will have to sell my Bracket car before i can build this one. I cant a-ford 2 race cars..LOL

Re: 72 mustang question
 

One reason the 1973 mustang 302 only came with the ram air hood, if you run the 73 351 cj 266 hp combo no ram air hood.But it seems like a good combo to run and there are not a lot racers running it and you get run in G&H.And if you need a set of those small valve heads I have a set.

Re: 72 mustang question
 

Technically to run the car with the 73 combination you would also have to change the grill and marker lights in the grill. The 73 has a front end all it's own.

Re: 72 mustang question
 

Guys, Robbie said he wanted to build a budget race car! G & H /SA..C'mon.
Rob, What happened to the 302 Maverick idea?

Re: 72 mustang question
 

Well that's kind of better than talking about D/E/F for a 72.

Re: 72 mustang question
 

Hi mark, someone offered me enough money for the car that I couldnt say no. I bought the 72 as a street toy but I was thinking about building a Class car out of it.Do you guys think I could do it for under 10k? I dont need a record setting car. Just one that will go under the index.

Re: 72 mustang question
 

Humm 10 parts at 1000.00 each or 20 parts at 500.00 each and how many parts do you need plus labor I guess you could try it.But if you are going to do it you may as well try to get the best that you can so that you don't have to do things twice.Check out what those two racers with the firebird and the camaro have done and they are just running the index.Even though you only need about 450 hp it just don't come cheap with these factory cars and engine.

Re: 72 mustang question
 

No, don't think so . Roll bar ,chassis work required in those classes.
What are you going to do about heads up runs? I know you'll be there to find them in later rounds. Much safer in U/SA
Bill is probably right about the weight, but I'd set the 302, C4 in it , take all the street junk off, and get it on a scale, or borrow the four wheel kind.
The 302 is so soft , you could stand an extra 100 pounds.
Get ahold of Mike Graham...BJ is gonna need someone to race in class!

Re: 72 mustang question
 

Well thats sucks. U/SA it is I guess. I have a spare motor, trans and parts for the 302. Guess I'll sell off the 351 parts. Sorry for wasting you guys time.

Re: 72 mustang question
 

Mark is right. Not going to build a E car for 10k. You can build a Maverick for less than 10k that will go 1.3+++ under easily. I have one. Not much worry about heads up with only 2 cars in the division. There are also advantages to being able to qualify where you want to. Mark knows what the combo needs for a converter.

Re: 72 mustang question
 

Mike will your wife be driving the maverick at the Las Vegas divisional, looking foreward to seeing it run.

Re: 72 mustang question
 

She will be driving at the sportsnats and the divisional. She is learning fast.

Re: 72 mustang question
 

Wish BJ the best of luck from me Mike. The Maverick makes a great platform for this stuff. :D

Re: 72 mustang question
 

Build the Cleveland...its not that hard or costly

Mine is coming together slowly, not much time for me to work on it this time of year I will be fluctuating between C and D/S depending upon how well I get the car working

Re: 72 mustang question
 

So are you going be running the Boss351

Re: 72 mustang question
 

Yes

Re: 72 mustang question
 

Ill be looking foreward to seeing you out and to see what a boss can do,the Boss is rated at 360 hp right.

Re: 72 mustang question
 

355

Re: 72 mustang question
 

Has anyone built a 4 door maverick? Would it be a good 302 combo? I know where I can get one VERY cheap. And it has a 302 in it.

Re: 72 mustang question
 

Yup. Gapp & Roush. :D

Re: 72 mustang question
 

Would a '72 R code be competitive in Pure Stock or is 330hp rating too high?
