The 327/325 hp was (is) the L-79 option. It did use the Holley carb. It was also available in Chevelles in '68. The compression ratio is 11:1. Better get out that credit card for some high test. If the engine code suffix is EP, ER or ES it is from a Chevelle though if it is date coded as '66 it may actually be 350hp (cool!). One neat thing about this engine is that you could only get it with a 4 speed.
