Ok guys,I am going drag racing in the spring.For those that dont know I have a 68 stang with a 466 560hp.I currently have 720in.lb springs in the front(very stiff)and 5 leaf standard height in the rear.I am planning to keep the rears for now and maybe clamp them.But what would be a good spring for drag racing in the front of the car?Remember I have an iron headed 460 so I have alot of weight in the front.I need something to allow the front to rise.As it is now with those springs the front has no lift at all so I have no traction.I was thinking about the Moroso trick front springs for the 428 cars.
Well throw me some suggestions please.

Bob - those are the front springs we've been using for years. They do sag after a while - maybe 3-4 seasons. On the back we have ordinary 5 leaf springs (rearced 2" over stock about 17 years ago) with Caltracs. Would like to go with fibreglass monoleaf but $$$ - probably back half the car with a 4 link before that happens.

When I removed my sway bar and added some 90-10 shocks.It helped to lift the front up.

Seems like 6-cyl front springs would work too.

I'd run the stock v-8 springs in the front with 90-10 shocks. Lowering the upper shock mounts will help too. Then clamp up those rear leaves and put Rancho 9000 adjustable shocks on the rear. Use Cal-Trac's or good slapper bars, if you're on a budget
Otherwise get a hold of Alex for the real good stuff.

Moroso is good for your application.
They are fine for big blocks.
They DO NOT work on small blocks!

Thanks for the advice guys.I have 3 way adjustable shocks now that I'm gonna stick with until I see how they work out.
I will clamp the rear springs also.
So Alex I'm gonna get the Moroso springs.But...And you probably knew this question was coming but there are three different rates as follows:

front end weight spring rate

1610-1680 242in.lb
1680-1750 250in.lb
1750-1810 260in.lb

Which one do you think would be a good starting point? All are for a mustang with 390/428. I have no idea what my front end weight is but I know the motor probably is around 650lb.
Steve as far as lowering the shock mounts that is a good idea and it obviously works but i still drive the car on the street.I will be just swapping out the springs when I go racing.The front
sway bar is already gone too.
I dont want to do too many things at once until I find out what works for my car.But hopefully with you guys help I will get there.
