Old school slapper bars and stick shift

[SSDiv6]

I cannot recall what the Waldo's ran in their Mustangs.
Nevertheless, if I recall, Jim Waldo ran slapper bars on his Mustang and that car hit hard in the starting line and ran fast.

Sounds like you need different tires as well. This sounds like a real torque beast. What gearing, clutch and trans? Launch rpm? If you added a hundred cubes and a stick, most of the things that worked before will have to be re-evaluated.

It made 540hp at 5600 and something like 520ft-lbs at 4500. It had a centerforce clutch that it was driving through. We just put a McLeod long style...forget the clutch disc off the top of my head.

Now the clutch is working well but the tires are blowing away bad.

I found an old pair of QA1's single adjustable on my shelf and we're going to try them this weekend. I never ran them, but at their highest setting they're very tight! He ordered some shock extensions, as it looks like the suspension is extending about 1" more than the shocks will allow.

Calvert's Shocks are Rancho's but with his name on them. Since Ranchos are truck shocks there's no Mustang specific listing but he will give you the correct ones. They are listed for the front of some Import 4x4 as I recall.

The shocks will help but unless the front end has the usual mods you're probably fighting a loosing battle here. Even CalTracs won't be a fix all unless you have an adjustable clutch like a SoftLok. I have tried and done most everything and still can't leave much more than 4500 and I consider a 1.42 60' as being decent. My 390 ran a 10.18 @ 132.25 last year which tell me I need to leave harder.

And I agree with the others about tires. Don't think what you buddy has will get the job done.

That 'stang is awesome!

The front suspension is a bit of a mystery at the moment. It's one of those coil over conversions...can't remember the name..want to say Kodiak but that's not right.

Anyhow after the first time he took it to the track I noticed there wasn't much front end travel. We got to looking and he had them installed with a spacer in the wrong place. The travel was 2"...after we corrected it, it was more like 4". Still, it seems lacking. I think the spring rate might be all wrong for drag racing, and the front still doesn't move much.
