thats such a typical response....what was that...maybe thats becasue most people have such a mild combo and all they want is a big freakin cam...if you want a x, how about you get some victor jr's will will use the power range of the x cam, or maybe some z304 ford racing heads which work well with the x303 cam, while your at it go ahead and run a tfs R or victor intake to take advatange of the power band....does that make sence, its a big cam, and it needs to breath, you need to have the entire thing set up right, like rick said, he showed you the specs and with wht ya got its a little much, I would even go to say with what you plan on doing its a little much..and I would say heck with shorties if running a cam that needs to rev...long tubes all the way....hope it all makes sence now, and no, running the e cam just wants becasue its a typcial responce...because its a educated responce, have you looked into the tfs stage 1 cam at all? How about a custom cam? Maybe people recommend stuff that they seen work...also you going with the stock short block? If so....I dont think that cam will clearence with the stock shortblock
