So a rod let go and made a hole in the block and pan in my LQ4. I have a 5.3 shortblock thats been sitting on a stand but apparently its an 2007 flat top 5.3 w/ AFM/DOD. So I guess I need to delete the DOD ..get a few more lifters, lift trays . Do I need to change the vally cover ?

Also i have 2 cams but dont remember which is which they are supposed to be 07 c6 & 06 Zo6 where can I check the Cam #'s.
3206 s20 7061 ..single bolt
06906l 1251 7552 21 ....3 bolt

Also I was wondering if I could put my 317 heads on it and what it would make the compression since stock its 9.9:1

I think its an LY5 or LMG but the block says R27 and L27

Its probably a LH6.
Yes the valley covers are different.
My compression with my flat top 5.3 and 862 heads
comes real close to 10.3 , so you should be around 9.5 .

blow thru carb 15 psi 15° on 93 w/ a/w.. been running the engine for 3.5 yrs now and it finally let go. I think it leaned out, I didn't see anything on the plugs or pistons detonation wise ill put up some pics
