I finally took my 69 GTO to the track. It has a 462, 87cc Eheads, RPM intake 750 APD holley, Crower 60919, ACR rods and TRW flat tops, Redneck 2600 converter, complete Robb Mc fuel system with #8 braided all the way up, Turbo 400 and 3:55. Even though the tran was rebuilt last year while the car was apart, it was a mess. Ran 12.85 at 105.27. As soon as I left the line it shifted on it's own to second and when I shifted to third it sliiiiiiiiiiiid into 3rd FINALLY. It pulled good but theres no way to run it like this. I read some of the old post this morning and ordered a TRANSGO shift kit. I'm going to see how much that helps or if I have to go farther. Does this sound right for a stock turbo 400???

[David Jones]

Jimmy something sounds amiss. My 69 GTO with a 400 and a 3.55 and a very mild hyd roller did a 13.2 @ 105 on Radial T/A's. Your MPH should be higher than 105.

[Half-Inch Stud]

Mr Jone, perhaps your ET should be way lower.


Many Stock TH400s can shift waaaaay sooon after launch.
Many Stock TH400s can sliiiiid into 3rd.

TRANSGO Stage 2 will fix those right up.
You will need to retool the Govenor inner weights for desired WOT shift at Redline.

Jimmy, you have a LOT more in that combo. We built a 455 couple of years ago with unported Edelbrock 87cc heads, Crower 60919 cam, and it made 505hp/551tq on the dyno, and pushed a 3800lb car to mid 11's at 118mph.....Cliff

[jimmy daniel]

Cliff,
I copied your advice on a motor build from a while back. That may be the one I copied. I also followed your advice on the fuel system. Only difference I remember is my Eheads have been ported and I don't think yours were. It makes real good power but drives right thru the transmission. I'm going to put the transgo kit it and try it again this weekend. I could tell there was a LOT still to gain. What else do I do to the tranny while I'm putting this kit in? governor??

Mr Stu, I think you might have missed my point. One can never tell with your replies.....

[David Jones]

I wouldn't mess with the governor until you can determine where it's shifting now.

[ta man]

What is your timing set at?What was your rpm crossing the line?What do you have for exhaust?

[jimmy daniel]

Timing is 36, not sure what rpm I was crossing at. Exhaust is Dougs best 4 tube headers with 2 1/2 exhaust but not sure on mufflers. The headers were capped.

[Cliff R]

"It makes real good power but drives right thru the transmission"

It's probably going to "drive right through the torque converter", let me know when you are ready for a 10" Continental unit to effectively hold all that power and run deep into the 11's in full street trim!.....Cliff

I agree with above. You should be 115-120 mph. Running out of fuel, major converter slip, or something else? Was the cam degreed in? -Jim

Cliff,
I may end up having to buy that converter but I'm going to address the trans first. My Transgo kit came in yesterday. I couldn't get anything accomplished in my 1st test with the trans shifting so badly. It shifted to 2nd almost imediately even though I had the shifter in 1st so I got nothing out of 1st gear. When it went from 2nd to 3rd it seemed like it took several seconds to get in there. After I get this trans kit installed, I should have a better feel for where I am. Then I'll move on to the next problem if there is one.

[jimmy daniel]

By the way, with it shifting to 2nd almost immediately, I had a blistering 1.893 60' time.

[JSchmitz]

Get that trans fixed first. It sounds like you lost a lot of time there.

[jimmy daniel]

With the trans fixed it went 8.07 at 85 mph this weekend. It was 98 degrees, HOT and humid!! I left the headers capped. The 60' was 1.795 this time (tenth quicker) and "feels" good but I know there should be a lot more there. They were having a big race so there was very little test time. The Holley with 74/84 may be too fat in this heat and we're going to undo the headers this time. It was an 1/8 mile race only but at the 1/8 mile mark it was really pulling hard. It's just going to take some testing.

[ta man]

Try bumping your timing up.

[jimmy daniel]

Just looked at my redneck converter paperwork. It's a part# 1110 10" "stalled slightly higher than stock" 2200-2500. Stall code 3-380.

[P@blo]

So you are using the $160 redneck converter? If you have the 10" the maximum HP is 400 and you will need to step up to the Redneck version of the Continental which cost more $$. The 9.5" is the one you want not the 10". I have the 9.5" with stall code 3-082 and it feels like a stock converter until you get on it.

Cliff, I know the conti's are a nice converter but this seems to be a unfair comparison. Now can you see why he pushed through the cheap $160 version of the redneck converter?

This is a 10" diameter stall converter stalled slightly higher than stock (approx. 2200-2500 rpm) for a GM TH-350 or TH-400 or Powerglide with a turbo spline input shaft (30 spline).



***If you have a 17 spline PG input shaft, you can buy this converter and tell us to make it for the 17 spline when you pay.



This high performance stall converter features the following:



* Anti-ballooning plates
* Brazed impellar
* Torrington roller bearings
* Dual bolt pattern
* Rated to 400 HP max
* 90 day warranty

and the better converter redneck offers:

***This is a 9.5" diameter 3000 stall converter for a GM TH-350 or TH-400 or Powerglide with a turbo spline input shaft (30 spline). If you have a 17 spline PG input shaft, you can buy this converter and tell us to make it for the 17 spline when you pay.



This high performance stall converter features the following:



* Anti-ballooning plates (will handle nitrous and/or transbrake)
* Fully furnace brazed
* Torrington roller bearings

Cliff,

I think it's time. Can you let me know which one I need?

[1971WARBIRD]

Hi Jimmy
is that the set of heads we traded?wanted to see how they would do.
