I have a 4.8 shortblock gen IV
I've seen the 5.3 and if im not mistaken they share the same bore - the difference is the stroke.
in order 2 convert it to 5.3 would i only need to change 2 shorter rod and longer crank.?

i know the gen3 5.3 motors also had dished pistons, except the VHOs - they had the same flat-tops as the 4.8
gen IV 4.8's/5.3 share the same flat top pistons..
why not just get a 6.0
all u need is the 5.3 crank with the right reluctor wheel for your aplication and the 5.3 rods
where did you get that info at? you might want to look into that a little moreQuote:

Little mixed up, the HO 5.3's had the flat tops and were aluminium. The VHO's are the same a 2wd SS
