I have a 07 Silverado 4.8 with a Intake, Exhaust, Wheatley Tune, and Longtubes, and i am about to buy a T224 cam with springs and i was wondering how hard it is to make my motor a 5.3.... I was told if I change the Crankshaft and rods that there it would be.. Is this correct? Is the bore the same just the stroke different?If im going to get a cam in i might as well do everything at once. Any and all help would be appreciated.

 

I might be wrong, but it would probably be cheaper and easier in the end just to find a 5.3, add your mods, then drop it in your truck.
You could then have the 5.3 work done and still drive your truck. Then when the engine's ready, swap it into the truck...

 

If you go that route then just drop a 6.0 in it . . .

 

x2

if youre gonna do a motor swap make it worth it

its like a girl getting a titty job and goin from an 34-A to a 34 B ... u know what i mean ...

 

The reason that I asked because i can get the rods and crank from a 08 5.3 for 100 bux and free labor : ) this is the difference right?

 

well thats a deal,ide do it.what the heck,u already have the block.are the pistons the same?

 

that's what I'm trying to figure out. I think they are the same

 

I am pretty sure the pistons are different as well. The 4.8s are different then the 5.3s i believe.

 

Should all be same as the 5.3l has flat tops now.

 

Nick,that s**t was freakin funny 'bout the ****!!! LMAO
