hughes whiplash cam and other cam opinions
Nothing wrong with those whiplash or thmpr cams. They give the idle because of the tight LSA. Everything hughes is overpriced IMO.
With a 4 spd the cam selection is pretty wide open. Whatever cam you choose, I'd install it very advanced from whatever the LSA is to get some low end grunt. This is where you can run a larger cam than you may think and trick the engine a bit with the cam advanced a bunch. I install 108 LSA cams at 100-102 all the time. Make the engine run much different than if in at 108.
