If I get that scoggin dickey 350 for 1298. what intake/carb setup, plus headers will produce the best power???? any one have this motor yet. the web site claims 240 hp and i have read that if I change cam it voids warranty. but I was figuring that the warranty would be a pain in the arse to use since it is all done by mail! any info would help my desicion need to get b-4 dec 31.
