Building a motor for my Challenger vert project and I am lost on what cam to use. Originally I had planned to simply go back with a stock type build and just add a cam. This had me thinking the Comp XFI 273. Then my hot rod side took over for a while and I started thinking pistons, rods, bigger cam, springs but that comes in around $2600 so now I am back to the stock build and reality of needing a good cam. Anybody got a recommendation for a good cam to use or any testimonials on the comp cams or others that are offerred?
