Nice trick for a 4150 holley

With a DP my right foot controls the secondaries. Me Likey. I can whaaaack them open from idle if I so choose. And I so choose, a lot! Sometimes I do it just because I can....Almost nothing amazes me more than idle to 7000 with tires ascreaming, and smoke apouring.Yeah, dump the clutch and nail it,YEEHAW!
My 750 Vacuum secondary is also mothballed, as are all the other stuff I ever tried.
