I've read on a couple of forums of ppl installing the L92s on 5.3s... everytime i ask how is it done, they don't know.... is it actually possible??? And if not, is there any proof??

 

the L92's are made for the larger bore... 4" i believe...

 

x2...

 

if your reffering to l92 heads/ on a 5.3(327) ur answer is "NO" 5.3's have a bore of 3.7X and (l92/l76/ls3 heads) require a 4.0 BORE, meaning that you need at least a 6.0 engine to run those heads . And a 5.3 block could SAFELY only be bored out to 3.8X . .in addition those heads have square intake ports.

 

Actually 5.3's are bored out to 3.905 all the time

 

yes 3.905 to make a 383 , but than again ur walls are going to be really thin, ur gonna have run a good water pump+radiator to clear cooling issues..

 

I thought boring a 5.3 to 3.905 would make it a 346, adding a long stroke crank would make it a 383

 

It could probably be done if you notched the bore, and moved the cyl head with offset dowls but I wouldn't run that large of a runner on a 325Ci engine.

 

im puting one in my 5.3 ill get u pics for my setup this weak

 

Your putting a L92 in your 5.3's place?? The 92's heads as stated need that 4.0 bore to work..
