Hey guys i need some help i have a 2008 silverado crewcab with a 5.3 its cammed with 228r.has full 3in exhaust long tube headers has a fully bulit 4l60e with a 3600 yank stall. also have 373 gears with detroit trutrac. i bought a 6.2 aluminum block with 823 heads motor came out of a 2008 escalade was wondering if the 6.2 fly wheel will hook up to my transmission or if i would have to take the one off my 5.3.? Im fixing to sell my 5.3 just want to make sure what i need off of it to make the 6.2 work on my truck before i sell the 5.3 and not be hunting parts that i had thanks

 

X2 for a response, I'll be in a similar situation soon with my 07 NNBS.

 

Well they don't have flywheels but they have a flex plate lol.

That 4L60e converter is different than a 6L80e converter, that pretty much somes it up.

 

Thank you for informing us n00bs.
