Stock acc. pump cam on Holley 650dp.
I just finished swapping out a Holley 750 V.S. for a Holley 650 D.P.
The problem I was having is there was a bog on part throttle
acceleration.(cruising at 40mph and roll it on it would just about stall).So I put on a 650 dp. that my brother-in-law had kicking
around.It was modified to run on a high revving 302 for road
racing.I jetted it back up to 67primaries and 76 secondaries and
put .25 shooters back from the .28`s he had.My question is that
this carb has a pink primary pump cam and a brown secondary
pump cam.It seems to work excellent and I was wondering if
stepping up to the pink cam would do the same for my 750vs..
Can anyone tell me if these are the stock cams or an earlier mod?
