Sometimes I pretend to be normal
I noticed that with my car too. I had a 750 and although it ran good, it really runs good with the 600. It actually scared the crap out of me. Its never broke the tires loose when it shifted into 2nd, this time it did and kept them spinning.. I backed out of that one.. Then I started to laugh!!!!Nope, Holley 600 vacuum secondary...
He tried having a 750 installed, but it ran better with the 600, so he put the 600 back on and sent the 750 back....
