Whew.. street mustangs in the 9's!!!!!

But I want someone to think about a statement where a guy tunes to nitrous and anything else possible to get under 10 yet says: "It will never have an automatic"

I assume he means, "so that I have the joy of shifting when I'm on the street" So... will he go to live axle?

It was. And I'd love an '03 Cobra if I never had to pay for repairs. =)

Here's a quote from the 2nd-place finisher, who slammed out a 10.79, demostrating what those in the know think of Old Iron:

"I'd like to put a C4, a live axle, and maybe a Kenne Bell or Whipple on it and go nines," Jerry says.

Nines, after swapping out the T56 and the IRS for a 40+ year old back half. Well, whaddya know about that?

heh, good point on the repairs -

if you notice just about every one of those cars have the 26 spline shaft/clutch and upgraded axle shafts

not to mention that a few of the motors have already been rebuilt...

but yes they can be VERY fast cars - the article is just about the ones with the irs and 6-spd. the ones with solid axles and autos i think run 9's, and are streetable

on mine i want to ultimatley go solid axle and kenne bell - but it sure aint gonna happen anytime soon tho, this machine is keeping me broke!!

I saw one in a showroom, and thought, "quite a car, but no f'ing way".

I did.. naturally, with that kind of yank, those upgrades are needed...

"C4" was what really grabbed me. I mean, not AOD, not C6. The same damned C4 I had in my first '67 C-code. The lighter weight, smaller C4 sure can handle a lot when built for racing. Relatively cheap, a proven design, and motors with a lot of area under the curve (like high-psi, blown modulars) make three speeds adventageous with the right convertor. The solid axle part in lieu of IRS interested me, too. "Which way is progress, in this sport" type of thing...

They'll do that. For my street '67 I'm pondering a 4-bolt 302 with a Paxton centrifugal. For that $, I should just drop in a nice cammed FE, but I could do the blown wheezer in two "phases". Still got time. It's gotta be very streetable regardless.

You don't need much handling at the drags. Getting the power down and keeping it in one piece is what it's all about. Since mustangs usually drive on the street and actually DO make turns once in a while, IRS is the better choice for handling. (now, if they could come up with a GOOD IRS is another issue)

It was just interesting to me that after all these years, the old design is still such a desirable combo. I wouldn't have thought that. Of course, I've never built a drag car.

Right... and the street cars are of course better suited for road racing, which has been discussed in another thread.

A good IRS for street or strip use? Both? What's wrong with it?
