Hi all, im doing a 1978 trans am restoration/ pro touring car. Its getting a forged 5.3 along with a pair of 62s. I need a manual tranny because it will be a daily driver. Where can i buy a 700+hp rated t56 with out giving a core back? Car will weigh around 34-3600 lbs. Havent chose rear wheel size. Will most likley be a 19 or 20 inch wheel. Thanks

 

A new T56 Magnum is rated at 700 foot lbs of torque and no core required.

 

Oops forgot to mention,
i believe the swap kit was designed for fbody styled t56s, any options for those?

 

Someone on here is running a stock T56 Magnum at over 1200 or so hp and doing long pulls and it is holding up fine.

 

Can a magnum take place of a f body t56 withought modifications?

 

The only difference is shifter location,the magnum shifter is slightly further forward.

 

Not sure that will work with my application, shifter is already far enough

 

Anywhere i can buy a fbody t56 thatll handle 700hp, even from a vender on here? Rpm only quotes prices with return of a core charge, i dont have a core so i need a new one

 

Add 1200

 

I'm not following?

The F body T56 shifter is the furthest back of the two, Maybe 6". I would think the Magnum would be closer to the original, no?

 

Brp hot rods said ill need a new tail housing with a magnum. Abd i must of read thevpost wribg, i thought it said the magnum was shorter

 

How much can a stock f body t56 handel?

 

More than you think it will.

 

RPM transmissions

 

do you think it will handle 600hp reliably? Im thinking of grabbing a tr6060 and replacing the tail housing

 

A properly set-up T56 can easily handle 600hp, just make sure the clutch's capacity is in the 550-650 ft/lb range.

 

OP....dude...get a T56 magnum and a new driveshaft. Stop with the nonsense...

what's the difference between a magnum and a tr6060 if there is any? I'm thinking of going with a magnum.

 

I run a 100% stock Magnum making well over 1200 flywheel HP and no issues. I don't launch it hard (yet); however I do run 1/2 mile events and make big power in 4th and 5th gear without problems shifting at 7800rpm. No manual transmission will last forever making big power but it sure is fun banging gears

At 14psi it made 1060rwhp... we run 20-22psi in 4th/5th doing 1/2 mile events. No idea what it makes at that level... but it is more than the tires can handle since it blows the tires off at 180mph shifting into 5th if you want it to!

 

Wow nice car. Looks like I need to grab a magnum
