Hi, I did a search on this but wondering what the difference is between these two motors. From what info I have found, they are both vvt and the l9h has flex fuel capability. I think I have found an l9h for a retro fit into my 69 Camaro and wondering if any mods differ from the L92. Any advice before I pull the trigger??

 

The L9h has an aluminum block as opposed to the L92's iron block. The L9h also has 821 casting heads which feature the lighter hollow stem valves. I beleave the older L92 had the heavy solid stemmed valves.

 

not all L92 are iron, i have one out of an 07 Denali and its alumn

 

L92 blocks are aluminum. I'm putting one in my 98 jeep TJ right now.
