Can the 5.3 crank be used with the 4.8 rods and pistons?

 

no the stroke is way different and the pistons would stick way out of the hole.

 

Pistons, yes, rods no.

 

yeah, guess i should have been more clear there.

 

so i'm assuming the 5.3 pistons are dished?

 

you can use the 4.8 pistons on the 5.3 rods and thats the only way thats going to work...
i did one about a month ago the truck made awesome compression and with the cam that he used it ran really good for a 5.3...

 

so you can cam stroke your 4.8 to a 5.3 with just the crank and rods. Also using 4.8L pistons will have more compression than the 5.3 pistons? If this is correct, what will the compression ratio be, assuming reusing the stock heads and gaskets?

 

arnt the l33 rods floating as apposed to the pressed 5.3 dish? just curious how this plays out
