1960 283 chevy

If he goes too fast he will automaticaly get the HP. Unless you have a really good 3 speed it will not run faster than a good PG.

I still want one for my 66 283.(now i'm crying) lol !

I think that the NHRA technical department owes the good Captain (and everyone else running a '57-61 Chevy with a rules-mandated Powerglide) a written apology, published in National Dragster, for waiting FIFTY TWO YEARS to legalize three speed automatics in these cars. Thousands of Turboglide cars were sold, beginning in '57, and they ALL had 3-speed planetaries in them.

How competent is a "tech department" that lets something like this "slide" for over FIFTY F****n' Years??????

There's NO TELLING how many races were lost, that might have been won by these cars, if they'd been allowed the 3-speed "replacement" transmission that was rightfully (and legally) theirs to use.

Instead of a heartfelt apology for their gross incompetence, they issue a terse acknowledgement that NOW (fifty years later) the 3-speed is "legal." and expect the Captain to feel like he's been handed a gift.

The ignorance of some people is only exceeded by their arrogance.

They owe him an apology for this long-standing mistake.

Do I think he'll get it????

HAHAHAHAHAAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAAHAHAHAHA HAHAHA!!!

Hold your breath...

Mike,
Any data to back that up? I'm curious.
Anyone?

Geerhead55 · 02-28-2009, 12:49 AM

The data was provided by Superstock and Drag Illustrated magazine many years ago. Granted the car in the article wasn't a 60' 283 car,, but a typical (at the time) small block Superstock 69 Camaro. The 'glide was quicker than the TH350.............................Danny Durham

Jim,

I don't remember us DISAGREEING on anything but "factory" figures on boost and monitoring it; how, why, and when, and if you'll remember, I eventually came around to ~your~ way of thinking on that subject after about ten thousand pages of posts.... so, I think that whatever "issues" we had dissipated when the dust settled.

I don't know if you knew it, or even cared, since it's not a Class car, but my street/strip/ "bracket" car is a daily-driver '72 Valiant 4-door sedan with a Vortech boosted 360 Magnum that is good for about an 11.80 @ 118 in the quarter, with 3.55 gears, which really isn't very fast, but adequate on the street, for a 70 year old geezer with an attitude... LOL!

Just telling you that because you seemed to think that ~I~ thought that "boost" was a dirty word.

Nope; it's "addicting"... need I say more????????

That was an article on Paul Forte's TURBO ACTION '69 Camaro SS/JA. He was still running a cam ground for a powerglide combo that made more torque and he had tire spin. Maybe he could give you more info about this but I dont think Jack will have trouble with tire spin.......lol.

I built a '91 Camaro for a customer, it is a low 10 second small block footbrake car. We broke our turbo 350 on Saturday, changed to a powerglide on Sunday and went back to the same track to test. Car was over a tenth slower with the 'glide. I built both trannys myself, the turbo was a stock 2.52 low and the glide was a 1.76, using the same torque converter. Car suffered out of the hole and lost most of the et. by the 330, I was driving the car myself. I think the biggest problem was the loss of gear ratio with that 1.76 low, probably would not have been near as much a difference if we had a 2.08 first gear. But that was what I saw in the comparison with a 3200 lb. car on 9 inch tires.

Greg Hill · 02-28-2009, 08:46 AM

The heavier the car the more et will be gained using a 3 speed trans. Since Jack's car weighs 4,000 plus pounds it should really pick his car up. Going from a 2.18 low gear to a 2.75 or lower first gear should really help get the car moving and not having a big drop when you shift should help it down the track. I would bet it would be worth at least .15 on his car.
