Re: What is the difference between an L71

A lot. The L71 is the 435 hp, iron head, tri power 11:1 compression engine.

The L88 is the 430 hp, aluminum head, high rise, Holley, 12.5:1 compression engine.

The first made about about 450 or so real horses with open headers. The second made about 550 or more real hp with open headers.

Many interal parts differences.

Rarity. About 210 L88s vs 9500 L71s, very rough numbers, but you get the picture.
