Wink vacuum secondary springs
Has anyone played with a lighter spring in their vacuum secondary Holley? I've got a 460 BB with a 750 cfm carb and was toying with the idea of going to a lighter spring to open the vacuum secondaries quicker. Don't know what weight spring is in there now and was wondering if anyone had any suggestions on this and did they see any improvement in the engine spooling up quicker on the bottom end without bogging due to the secondaries opening too quickly.
