Aryan's 73 Mustang

A few was asking what kind of breather I was making. It really was more of a forced air deal than a breather.
16 gauge sheet and cut out a circle bigger than the hole in the hood.

While in tow I keep the breather element on it so The engine doesn't swallow a bird.

You get a small look with the foam and the way I fixed it in the pic. The picture show us trying to get the fuel problem fixed I had. Trying to adjust the fuel preasure with the gauge on the other side of the car doesn't work to good.

All the time put in to getting the line lock working was nothing but a waist of time. Running up into Ohio to get a t handle and making it work when it didn't fit.

Doing a burnout with the line lock left the car spinning out of control. I almost took the cones out once and then another time I was too far over and the tech had to back me up from where I got sideways and could not see I was over too far.

Slicks where same preasure on both sides and I had the steering wheel lock all the way over trying to steer out of it. This thing would kick the tail end over faster than I've ever seen. Amy thought it was cool. She wanted me to do it again so she could shoot video. I tried to explain that's NOT what you want to do but I don't think she got it. lol It was nuts. After trying the line lock a few times I ditched it and just used my foot brake. The car stayed prefectly straight through all three gears as I burned out. Not sure why it will stay straight using the foot brake and not with the line lock unless maybe it's not locking enough fluid to hold both front tires and it's walking the loose one forward. So anyways looks like the line lock button will become a nitrous button.

I was trying everything to get the car down a few tenths. It just wasn't happening. The car was having fuel problems at first. I set the reg when I put everything on and it was fine. First run the car wouldn't stay running. Came back and thought it was the rev limiter that was built into the tach so I clipped the wires. Done another run and it would not make it through the 1/4 before the shift light. I checked the fuel preasure and it was way low. I turned it up to 6 or 7 pounds and made another run. 1st 2nd 3rd shift light is on and I'm a long way from the 1/4 mile mark. I tried to shove the gas pedal through the floor. It will go or blow! I must have went through the traps at well over 7K.
I get back out and start looking over things. One of the guys pointed at the fuel preasure gauge. 1 1/2 pounds of preasure??? What's the friggin' deal! I adjust it again and set it at 8 and leave it. After that I made it through the traps with plenty before red lighting. So 3 runs I was running lean, REAL BAD! I'm not sure what was going on with it. The pump and reg is brand new. It never did it anymore and I check every time I came in off a pass, the preasure was right where I put it.

The cars pulling harder at top of the RPM range than last week but I think the battery drain wasn't letting it run right. I ran the Yaris off it last week to charge it. This week I didn't. The car started slowly breaking down with a hi RPM shutter. I was shifting at 6600 and a few runs in it started to break up at 6300. I figured I move the shift point down to 6100 but then on that run it started shuttering at 5800 rpm's I think with the fans, water pump, 140 GPH fuel pump that it just doesn't have enough charging system to run the car right.
My 60' times went from 2.3 to 2.0 still bad but better than last weeks.

The engine puked oil all over the side of the engine. I got worried I burned up ring or something running it lean like I did. I took a compression test on it and all 8 have 145 to 150 pounds of preasure. So I guess the bottom end is just fine. New goodies are on the way. Chevy HEI set up to fit a Ford. Stuff to put on an alternator on and a few small things. This is my last step in trying to get a noticable better run. If this doesn't work then it's a street car from here on out.

Something I was thinking about today.Do you have any bigger carbs laying around? A 600 is kind of small, even for a 302. The 289 I had in the Granada was just a flat top motor with a .500 lift hyd cam and the 2 450s on the tunnel ran worked fine. I wouldn't be afraid to try something as big as a 750 if you have access to one.

I have a 750 Vac/ Sec/ that I'm going to put on my 33. I thought about trying it on the Stang but wasn't sure it would help. I'd love to get a 750 double pumper for it but those are getting pricey these days.

Ive got different size carbs to test with if ya want next time...just let me know

I have read several times that vacuum secondaries work well with automatics but I prefer mechanical secondaries myself. As far as prices go, I would hate to pay what they get for a new carb without knowing EXACTLY what I need. Too pricey of an experiment for me.

After I get everything else running right I may try the carb. It just has too many gremlins right now.
Hopefully this new box of toys that Aryan opened will fix some of it.
