Do you know if yours might have been a 2 barrel engine??? I've never seen the low compression engine on a glove box decal list....

My engine is the original engine (just rebuilt and punched to 402), so it is true to being the L47 4 barrel 396 indicated on the placard but I've never been able to verify or find out what that L92 low comp designation is on the RPO placard.

There is a L66 designation for a 396 CID 2-bbl V8, though so there may have been that option available on the '68 model year.
