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.SteveW

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.
