nnbs 5.3 block to 6.0 what is needed
hi all
i know this is a common question but its different
way and nothing to find in search
my car specs are in the sig
if i want to swap the new 5.3 (LY5) block
to the old model 6.0 ( lq4 or lq9 ) what would be needed
because i heard they r different for the gen IIV
also the stage 2.5 heads i have would work on 6.0 block right?
because i can find those block for cheap here but the new models parts arent avail that much also i dont want to spend much on it
so if its easy am gonna do it soon since am looking to make 430-450 whp N/A
after installing a bigger cam and rebuild the transmission
(i would appreciate any ideas to reach my desired HP)
thanks guys

Have to use the new 6.0 bc of the 58x crank reluctor. Just get a new 6.0 and drop it straight in no other modifications necessary cept for a nice tune in the pcm. I've heard of adaptor boxes but I think they only allow you to use the new engine with the previous generation computer used in 03-06 chev pu's. Katech I think makes one of them.
