Did I screw Up? With my cam.

[Chaplin]

Big-Boss-
Sorry to have to tell you this, but I have to agree with everyone. I had a 428 that had Comp Cams' 292H cam in it- the specs on that cam are: duration @ 50 was 244/244 with .561 lift on intake and exhaust. Like you, I do all of my driving on the street and back country roads. That cam had horrible throttle response in the lower rpm, idled lile a pro stocker, vacuum at idle was about 4.5", and the engine didn't really begin to smooth out until 2800-3000 rpm. I disliked the cam so much, and found it so unpleasant for the type of driving that I do, that I wound up pulling the motor to change the cam. (Of course, when I had the motor out I decided to upgrade to a stroker, but that is a different story .)

Anyway, for the new motor (472 cubes), I picked a mild custom ground hyd roller cam from Crane- duration at .50 is 228/234 and lift is under .600 with 112 lsa (I actually was going to install this cam in the 428 before I decided to go with the stroker). This cam is night and day compared to the old. The engine has a little lope to it at idle, but idles nicley at 800 rpm with about 12.5" of vacuum. And it runs smoothly and pulls hard from about 2000 rpm and has so much power in the rpm range that I normally drive (2500-4500) in it is an absolute pleasure to drive this car now.

If you haven't installed the motor yet, I would seriously consider taking Patrick's advice and eating the cost of the cam and swapping it to something smaller. You will be much happier.
