Marlin,

The configuration of that fuel pump appears to be identical to the one installed on my 1969 (part number 6440482). I do know that during 1967-69 the L-88 Corvettes always received a different fuel pump than the other high performance big blocks although I haven't done any research to determine what the internal differences are. I can tell you that the external configuration is the same as the other Corvette fuel pumps used during that time period so if installation of the pump in the photo is not possible due to clearance in the Camaro subframe (DISCLAIMER - I don't know this to be true and have never attempeted this installation so I am going by Marlin's original statement), then the same would hold true with the L-88 fuel pump. If the "MV" code engines were originally slated to get the L-88 fuel pump along with the L-88 carburetor, I can see why the engineers would note this.

I have seen the fuel pumps installed on L-88 Corvettes (and one ZL-1 for that matter) as well as a couple of ZL-1 Camaros. The fuel pumps used on the two cars are VERY different in appearance; there had to be a reason for this.

I believed (like Joe) that the carburetors for the L-88s were all 850cfm models with mechanical secondaries and dual accelerator pumps. However, I'm beginning to think that this may only be true for the 1968-69 L-88s (and ZL-1s). I'm showing the original carburetor for the 1967 L-88 as part number 3886091 (Holley List R 3418 A) which is an 850cfm but with vacuum secondaries and a single accelerator pump. The 1968-69 L-88 carburetor is 3925579 (Holley List R 4054 A) which is an 850cfm "double pumper" (can you confirm these numbers Joe?). Kurt, you had mentioned in a previous post that Fran Preve knew the carburetor on the "MV" engines was changed to the L-88 unit. If you have the part number from the bill of materials, can you tell us which (if either) of these two part numbers was used?
