the forged shortblock will be ready next month and once its in, the boost will be upped and new heads/cams will be on -around 400 rwhp. after all thats is said and done, I may swap the eaton m90 for a KB and trhow some street radials on. if I do this, how much HP can the T3650 and the stock rearend handle on hard launches?

 

you might need to look in to a tko 500 or tko 600. i don't think the t3650 is gonna hold under hard driving.

 

It's the torque that you need to worry about.

All the rear end will need is an upgraded diff and axles.

As for the transmission, I would recommend a upgrade.

 

those are rated for 360 tq. it will probably last for a little while for you to save up for a TKO600 (the exact same tranny, just beefed up a little)

 

any idea on reasonable prices for the parts and labor of the tranny swap? what about the differential and axle replacements?
