 Hi,I recently bought and rebuilt a 1.12" 4100 carb that originally came off a '64 289 Comet.  I noticed the powervalve in the rebuilt kit moves a lot lighter then the one I removed. Since I learned here that power valves from a Holley fit in a 4100, what would be a good choice for my very mild 289 (performer cam, home ported stock heads, tri-y headers, performer RPM intake, C4 and 3.00 rear end)
