I'm going to be putting a series 2 into my Oldsmobile with plans to go turbo soon after. I was wondering if i could use the L67 block (for the lower compression when i go turbo) with L36 heads, intake, and stock pcm. I know they'll fit, but would the lower compression effect the pcm? Of course ill be tuning the pcm after the turbo setup, but i was wondering if i could avoid the hassles of tuning while i get the engine up and running.
