Manual Trans Help

[Chris "drooze" Wertman]

I am very curious about this thread, I have "considered" also running the DP as a stick car.

I likes gears.....and Im good at shifts....(better if I can do it with my foot but...)

I am seeing everyone say go aftermarket, pretty much across the board.

I have a new T56 Viper tranny that came with the DP car (ours didnt come with a "core" as many others did, but a current year new tranny)

So.....

The ratios are
2.66
1.78
1.30
1.00
0.74
0.50
2.90


I would obviously never get past 4th (gated plate to lock them out ?)

Is there anything "wrong" about running this trans ?

I know they can handle the power if built right, no problems.

What other things might be "run into" using this combo ?

The other ratios readily available are
2.97
2.07
1.43
1.00


Just thinking ....

I like the idea, but Im not shelling out 5k+ on our next auto PLUS a gearbox, IF I could use th viper tranny I would consider it, otherwise its going in my 72 Chally.....

Cheers

Chris

We ran .88's with the stick ,but I suppose, with the high dollar lifters and higher seat pressure , you could run it through okay with 5.13's . That might help with overall gear ratio lower. I don't see where a lightweight double or triple disc setup would work . It seems to need some flywheel weight to launch within the rpm range.
The automatic cars work very well with a 4.56 gear, so you see that all that extra gear required for a stick is not a good situation.
Bottom line ,as I said; Too much weight, not enough rpms for a stick.

Build a 67-8 car if you have to have a stick shift Pontiac.

Thanks for reading and remembering those articles.
