Even the XE option is much less than a match for the RPM intake, but will no doubt deliver several more ponies to the rear wheels. Neither will have any "rump-rump". Your mom will drive it happily. Ok - ok, the reality (for me) is that if I'm going to spend money & time doing a cam change, it MUST have two things:
1) At least a noticeable rump, and...
2) Some horsepower to go along with that torque.
C'mon man, break down and pop for something that will tick off the wife and send rice burner owners running for their X-Box games.
Having said that, my 429 Torino has a very mellow CompCams 268H (218* @ .050) in it. I never drive it anymore. Too mellow...
My Fairlane on the other hand... Well, with 250*/258* @ .050 I love driving that thing, primer & all. Rumpity- rump.
