im rebuilding a BW t-10 to go behind a pretty radical stroker small block and im not having any luck sourcing new upgrade parts. is it possible to put bigget input and tail shafts, like in the super t-10 in the unit im building? thanks guys

aAnything is possible. My company is one source for T10 parts. The following applies to ANY source though.

The T10 was made for so long (Since 1957) that you cant just start field stripping it and replace parts. Tell us what you have and what you're looking to replace and most importantly what youre going to do with this trans. It may end up being more feasible to sell it and buy a new Richmond T10

Or a Muncie :-D

tranny is going in a 67 firebird that im gonna road race/street drive. i got the tranny real cheap and have read that you can get lightened t-10 gears for about 100 a pop. im just wondering if its possible to put bigger shafts, like the ones in the super version, in my box. tryin to do a budget racer/rod project

opening cases up for the 1" pin (at least in the muncie world) goes roughly 200 bucks, Id avoid the 9310 stuff because it doesnt like heat cycles and longevity can be a concern. What I would do is use the best quality synchronizers available and pick a gearset that you want. Theres a zillion T10 ratios.

Its all been done before but by the time you get the lightweight gears and they exit the party after a year or 2...I doubt its going to be 'budget' anymore. I'll bounce this off my chief engineer; he had some italian T10 parts made back in the 90s. I suspect youre still going to be in this for 1000 bucks or more

so leave the shafts alone, pick a new set of gears and just stick it back togather? motor should push about 650 crank hp

If you don't launch the car hard with really sticky tires and a triple disc clutch; it will last awhile. If you put sticky tires on the back and a really agressive clutch...650 will break...something. You need to have a buffer in the driveline 'system' to soften the shockload you're going to create on a hard launch. If this is more roadrace and street DRIVING than sidestep the clutch at 5krpm....it'll live for awhile
I have a lot of customers that use saginaw 3spds behind big motors in roundy round racing. The trick is to not apply power until you're in high gear and shift like my grandmother. You dont have that option realistically, but without a dragstrip launch you'll have some sustainability.

There is a roadracing gearset available for the 'Muncie' its a super close ratio and does really good with 3.73s to 4.11s or higher. An all new trans is 2grand and can easily take what you're throwing at it. I can turn you on to some T10 guys, if you want.

So, use a soft hitting clutch and something other than an all out race tire and you'll be okay till you miss a shift. Save your money for a richmond t10 or a supercase muncie

i alread have the tranny so thats locked in. i just need to pick a ratio then i guess, where should i look?

[AutoGear]

Where are you located?

[freeskier]
