Hey guys, I am looking to switch up the Silverado a little bit.

I am planning on building a 370" 5.3 base motor with a set of LS3 heads, g6x3 cam and other bolt ons. The truck is currently a 37k mile 2006 rcsb 4.8/5spd truck.


Question is, what all is involved in swapping my 5spd out for a t-56 setup?

Any help is appreciated,
Thanks!

 

How are you planning on making a 370 out of a 5.3? lol

 

Would a 6.0 block be better suitable? I have read where 370 is possible with a 5.3, no?

 

biggest you can get a 5.3 block is a 346.. sooo yes u will need a 6.0 block to build a 370.

 

Cool.

Any tips on swapping the 6speed in place of my junk 5spd? Just gathering ideas/advice and parts.

 

there pretty easy swap like i've been reading just need slave cylinder out of a f body then clutch cross member might line up idk i think some of the later 2000 cross members line up don't know about an 06 u need shifter made full console if your going to go that route 4l80 yoke i believe bc the spline is different on the out put shaft then the nv3500 and drive shaft i yet to find anything on

 

I just did this swap. Automatic driveshaft. If you use a stock location camaro shifter then you will have to remove or modify console and make new shifter hole. I used a kieseler shifter relocation setup and it put the shifter almost in stock location. ls1 slave and use the lines etc out of your slave, knock the roll pins out and swap stuff.
