If by some act of *** a '73 455 SD T/a and an '89 TT/A lined up on the main drag ,who would win? They both ran low 13's without a problem.

 

TTA without a doubt

 

Agreed.

 

IMHO, second gens were beautiful, but were POS's in many respects

just as most cars from that era

 

I sort of agree. I had a '76 TA, most reliable car I've owned. Only got 12mpg and was slow, but nothing could hurt it.

 

the SD-455 would whoop the living **** out of a TTA it ran low 13's stock and thats back in 73' when they still had the rock hard bias ply tires, on a radial it would be a high 12 second car

 

Then how come for years, not sure with new Ram Air TAs, but the TTA was the fastest production TA ever.

 

TTA's run low-mid 13's. The other car is fast, but I think they run 13.90's. Considering both are stock of course. I say TTA here.

 

point i was making is dont forget when they tested those engines back in 73' that torque monster 455 with with 225/70/15 bias ply tires would just melt the entire 1/4 mile, the TTA will pretty much hook and go givin the better tires. also the TTA was nearly 1,000 lbs lighter and the SD-455 had 8:1 threw horrible exhaust and a weeny cam. check out the pure stock drags, SD-455's are all low 13's high 12's with fatter radial tires. the SD-455 was the mother of all pontiac engines thats forsure

 

Everything I have seen for them is high 13's-low 14's. But thats all I have seen.

 

it really depends on the setup, the cars in those days varied setup as much as diffrent chicks ******* sizes the TTA was basically just one setup, the SD-455 could have the auto or 4-speed, 2.73-4.30 gears and other option, the most common test is a 74' with a auto and 3.08 gears, the test says it was done on a 40 degree day and the car spun the tires 60' and ran a 14.1 but with better gears, traction and a 4-speed the times were much better

 

I think you've got the RA TA's and SD's mixed up, the SD ran 13.54 in 73 with a serious traction problem( They run much quicker than this ,even),and the 70 RA IV ran 13.90 in 70.

 

Either way, I guess it would be close, but I would have no doubt as to which I would rather own. Just look at shrp1's car, not much modding and he's hoping for 10s..Wow.

 

They're both great cars, the SD is also easily modified ,a set of slicks, frame connectors,traction bars ,headers ,and tuning and it would pull low 12's high 11's without even thinking about it.:rockon:
And I know what the :hail: TTA can do thats why Im asking ,to see what everybody else thinks,cause Im not sure who would win.

 

you've got it right soild, the SD with a hotter cam, headers, put dual exhast on it and slicks and they will run high 11's all day, on a tta with some bolt ons would be 12's no problem, it would be a showdown but i'd have to give it to the SD-455

 

SD's had duals from the factory ,my '73 400 formula came with duals even ,dual exhaust was avalible thru the end of '74.But you could deffinatly benifit from aset of 2.5" duals. as for the cam that was a nice ra iv spec peace with .470" lift and 320* duration ,a solid cam would really wake up an SD like you said high 11's would be no prob.Shaving the heads down a little too would be cool too.SD'S RULE.

p.s. how do I join LALA racing?:lala:

 

OK I found an official time for that car and it is 13.54@104.29MPH. I still say TTA. Keep in mind we are talking both cars all stock here or close to it. 1 things for sure though, it would be a good race.

 

Thats the same time (minus the mph) I posted about 5 posts back keep in mind thats on stock $#!+ tires, and magazine times are always a little slow ,I mean look at the test hotrod did on the TTA when it was new 14.21 @ 97.8 mph WTF they must of had an 89 year old women driving that thing, you can't beleive those mag tests ,cause both the SD and TTA where alot quicker than what hotrod and motor trend would have had you beleive.

 

Chaos rampant,
An age of distrust.
Confrontations.
Impulsive sabbath

 

On and on, South of heaven.:hail:
On and on, south of heaven :rockon:

 

now you can offically join bow to la la racing

 

:hail: :lala:

 

Only way to know is to race.

 

That's a really good point. All the times from the 60s can basically just be forgotten about because of the pencil-width, hard as a rock, bias-ply tires. I have a test in front of me for a 67 L71 Vette that ran 13.8@111mph

 

They ran the '62 421 SD to a 13.9 on frickin 6" wide bias plys to!

 

finally someone with a brain! yes i really get annoyed with people saying "this and that new car ran just as fast or faster then the old cars" but what people just dont factor is way back in the 60's and 70's cars has at the fattest a 225/70/15 rock hard bias ply tires behind torque monster engines that 60' would only be tire smoke, one test i saw that was great was in 68' the GTO ran a 13.7 factory stock but on slicks ran a 12.9

 

Early 60's SD-421, now thats what im talking about heres one for you,............waiting for the hour of reprisal, you time slips away,.......(guitar),......

 

:hail: :hail: :hail: :hail: :hail: :hail: 410 HP 13:1 421 SD !

 

Its raining blood, from a lacerated sky,bleeding its horror, creating my structure,now I shall reign in blood.

 

We all talk about not getting traction if we stab it off line,I dont get any with my buick with modern day 9" wide radials, but you DONT want to know the traction problems the pontiac 400's 428's and 455's had when they were running on stock tires, trust me it sucks,its WAAAAAAAAAAYYY to easy easy to do a burn out at 1/2 throttle and without even trying.

 

:rockon: :rockon: :rockon: :rockon: :rockon:

 

absolutly, i had a stock 70' buick lesabre 455 with only duel exhaust and the torque in that thing was unreal, at 1/4 throttle it would melt the tires 1/2 a block and that was on a 235/60/15 radial tire! the torque of the the old BOP engines is unmatched by anything out there today, amazing they got 13's out of the cars on those crappy tires back in the day, imagine if they tested them all on good tires 11 second 1/4 mile from the show room floor

 

Tell me about it! BOP motors w/ 510 ftlbs. of torque are nothing to laugh at. My dad talks about the Grand-Am that he put a 455 w/428 HO heads in, It was a one wheel peelier ,and he constantly had to get a new tire for the rear Beacause he couldn't Contain himself.

 

I'd like to run a 302 Z28 and COPO 427 on good tires these days.

Imagine that.

 

I have a CHP from 1993 when they ran some Chevy legends. Man what a good magazine that one is. They ran the cross-ram 69 302.......

 

i still say the TTA, and mod for mod i still say the TTA, be one hell of a race though

 

For looks and glory the TTA.
