Isn't a a six speed manual T56 a full manual too? LOL. (I just had too LOL.)



Seriously though , I prefer my lt1 to stay T56 also.

Even though I prefer to keep it a T56,..... when you think about it, shifting 5 times WITH a clutch is alot more work than shifting 2 or 3 WITHOUT a clutch obviously.

I don't mind sacrificing ET on a daily driver to have what I want though.

If you are shifting 5 times in the 1/4, you have major gear issues !!!!!!! lol

being that the cutout was closed, which is about an 100whp difference on my car, and plenty more area under the curve is a starter. 141 was bouncing the limiter, way before the traps, and the car was still climbing hard at that point. i had several other big factors working against me, but i feel like a ricer repeating these issues over and over again so ill just shut up and let the numbers do the talking.

i am not doubting ur knowledge at all, just simply spilling the beans. i figure i can pick up another 10mph in the gayth (only traped 101, serious traction issues)......which should in turn help the top end. i got some tricks up my sleeve. i was pretty surprised myself with the performance considering the combo. as a gauge, when i was still learning to handle the car, it was pulling pretty hard on a 142 trapping R1..... we'll see

Yep, and if you'll notice, I don't have one of those either.

I used to think that way also, but when I had my 700r4 torque converter lockup on a switch, it really turned into a pain in the *** after first few weeks of driving it. You would think that flipping a switch every time you get up to speed isn't that bad, and way easier than shifting, but it really grates on you after a while.

One of the goals of my car is for it to be stupid-fast and for the driver to have to do NOTHING special or out-of-the-ordinary when driving it. My 60 year old Mom borrowed my 9 second car a few weeks ago and I didn't have to give her ANY special instructions . . . except to not floor it.

Your car definitely rolls out, and I'll be asking alot of questions about your setup if you break 150 mph on pump gas OR race gas, but it's a pretty tall claim to say that you could break 150 based on a sub-optimal 141 mph run. I know I've made dirty passes at 141 mph, then clean runs at only 143. I made alot of changes to my combo (cam, cid, converter, gear, wheels/tires) to get to 146 mph for a gain of only 3.

I thought the same thing until I made some good 1/8" runs. I picked up 10 mph in the 1/8th and 1 or 2 in the quarter. I had run 105 in the 1/8th and 140 in the quarter. I finally got 115 in the 1/8th with better tires, but it only did 142 in the quarter.

Don't get me wrong, there's not too many of us running the 76GTS near its limit on v-8's, so I think we need to stick together and learn from each other. But, I'll be very interested to see how your car does with the issues straightened out.

ur probably right. i know im thinking a little optimistic right now...lol. everything you said has come into my though process, im just being a little naive. ill be shooting for that 150, i know its not done much with a 76gts on my cubes, but most importantly i will NOT go at it at all costs as its my toy for the street. using street street style suspension and tire size, im hoping for a 9 second pass and upper 140s.....if i dont get it, it wont bother me too much. im more than happy with the performance of the car for what it is

That would be very important!

Sorry for the highjack, but what are your cam and cubes?
