Hey Bob...in answer to your question of the day, the ZLX was a Motion promoted big block configuration ....L88 shortblock with iron open chamber heads.

Additionally, I don't believe the L36 was <span style="text-decoration: underline">ever</span> intended for medium duty work. Medium duty trucks had 366 and 427 tall deck engine configurations; 10.200-inch deck height versus a passenger car deck height of 9.800-inches. As many are aware, the extra deck height was incorporated so that a four ring piston could be used on the medium duties.

None-the-less, thanks for the Memories! [img]<<GRAEMLIN_URL>>/smile.gif[/img]
