Need help with owners of x-303 cams & Victor Jr. Stuff

I do believe the Victor Jr runs a "air gap" design which inherently makes for a taller intake... so you might have issues there. Those heads and intake are mighty stout peices, I was going that route I wouldn't opt for the X cam. I'd go custom or call up E-brock or comp cams and see what grinds they recommend. There are just too many newer and better cam profiles out there. Ramp rates and such have come a long way over the past few years. As for 400rwhp... that is not an easy thing to accomplish even with a 347. At one time I thought 400rwhp out of a 347 was a walk in the park until I thought I was going to build one and started looking at combos, there are not a whole of people that have done it. 370-380 is more the norm of a pretty stout 347 from what I've seen.

i dont have any personal experiences with the X cam....but it seems to me that lots of people who go to X cam have nothing but problems....go custom

I have seen several AFR 185 combos making 390 - 410 using comp cams

that's because they dont change their lifters out and the X cam basically tortures their lifters to death with its big ramp rate and duration.

I'd suggest you toss in for a set of hardened pushrods, aftermarket lifters, and a throttle body. Oh, and throw that adjustable fuel pressure regulator in the trash before you destroy your fuel injectors. what do you have your rail pressure at right now? heh.

my first cam in my old 94 was an X, I absolutely loved the idle it had but i didn't have the rest of my car setup for it and it did a little damage

swapped to a F cam and a better setup and the car ran very nice and still had some chop to it, then sold the car doh!
