Boss Mustang stocker

[Bill Diehl]

Thanks for the suggestions Bill, I have the open tracker double roller perches (nice pieces) don't know what I am using for shocks yet, I may spend the money for custom pieces. I planed to install the bearings in my control arms.

I sent a letter in requesting clarification on this and the cam bearing, as it looks like I started a sh*storm with that...it's better to find out what the deal is sooner than later.

What did you use for front springs?

[Bill Harris]

I am not absolutely sure what the front springs are. When I bought the car I am pretty sure that Denny said that they were from a 351 car. It sat a little high in the front and I cut half a coil off them which got the height just about right. I have about 1" of downtravel at rest, perhaps a touch less. Remember, I have a 750 lb chunk of cast iron sitting in there . I gotta believe that the Boss 351 is 150 lbs less than that.

The boss is lighter...I have access to springs, when I get it all together and scale it I will do the math and put whatever it needs...they may even be dif from side to side

Are you having springs made Bill ? I need to change mine as well but all I've come up with are a pair for a Maverick off of rockauto.com.

The compressed standard ride height is aprox 12" . I am not saying this is what to use but moroso drag springs for the ford are 242 rate designed for 1610-1690 front end weight.

If you scale the car you can select springs from many places, here is an example

Typical drag race stock suspension front springs are longer with the correct rate to get the ride height set back to standard, as in the case of the mustang aprox 12"

without scales and a calculator you are just "guessing" unless you copy something that somebody else already uses (edit, you want to take the free length of the spring and do the math to set ride height...example, 1600 front end weight with 800 on each tire and you want to get to 12" ride height you would need a spring with 16" free length x 200 rate = 12 ride height.....but in the real world the rate increases as the spring is compressed, you would need to take that into the calculations also...and reread the paragraph above this, drag race front springs are usually longer than stock)

some springs will be ground flat at both ends so you will need to cut a coil on one end to get a pigtail....you need to figure that into the calculations.

Then the best setup would be track test and adjust

Got this finally.....the dog is wearing out the UPS man....still waiting for the crossmember, soon the front end will start taking shape

If the scale @ our track is right, my Cougar is about 1950lbs. for front weight. As it sits in the garage Im showing 9" long sitting 1" off the bump stop. (Its a little low) So for a 200 rate spring, is that about 14" long free length ? Thanks for the link, did not even think to look there.

Edit: They dont have a 14 so, I guess, start here : PAC-SR16x5x175

That is not the only place to get spings, check some others out. not so sure I would go by the track scales ( I guess it can get you in the ball park) it is made for weighing the whole car
