I have a couple motor home 440's with 452 heads that I'm going to use to bracket race in my 67 Dart. Trying to figure out what cam will yield the best times with my set up. I don't mind changing out the valve springs to upgrade the cam, but would like to use the heads and lower end as is. I'm looking for recommendations from people with experience raising the performance of these motors, as they are pretty common. I have not weighed my car, but it is a 67 Dart with 440 engine/727 transmission/9 inch Ford rear end. Nothing has been done to lighten it. The transmission has a 2500 stall converter. Rear gears are 4.10. Motor mods include Schumacher Tri-Y headers, Holley 850 double pumper, Holly Street Dominator intake, Holley electric fuel pump, and electronic ignition. I've read about the Hughes "Whiplash" and Lunati grinds, but haven't heard what kind of times guys are getting out of them in cars similar to mine. Perhaps other cams are a better choice. Interested in some feedback from guys who have had good luck with a similar set up. Thanks
