Yes it was an 850 CFM Holley but it had vacuum secondaries. Maybe the engineers at GM should have asked mreid what to use since their years of racing experience and dyno. testing must have been wrong.
Like I posted earlier, NO manufacturer used mechanical secondary carbs. on a production car, even limited production ones destined for the track. Not Ford, GM, Chrysler or even Shelby. There is a reason for that.

Here is a quote from a corvette forum,
"68 and 69 l88's used a holey 4150 p/n R4054-A OR A 4296-A (ALSO USED ON THE ZL1) GM P/N 3925519 AND 3955205 respectively.

I stand by my experiences, I am not an expert.
I am sure your customers liked the VS carb, I did too! But the MS suited my driving style better.
Good debate though.
