Hi All,

I bought a used SPF with a Roush 392 and my information states that the engine has a proprietary roush cam. The car came with Inglese 48IDA's on it but due to an engine failure the car was rebuilt and assembled with a Performer RPM intake and Holley carb. That was a couple of years ago and I've always wanted to put the Webers back on so I yanked off the intake manifold and am prepping the engine for the Webers. I have essentially no experience with engine building and I really don't know much about the specs of my engine or cam. I've read a lot of posts that discuss lift, duration, etc and I'm almost embarassed to say that this doesn't have much meaning to me. I do know that the car ran strong with immediate throttle response and insane power when the Webers were on it but there was definitely some popping when decelerating and my plugs were BLACK when I checked them. There was a lot of dark smoke from the exhaust pipes, too. This may not really matter anymore since I'm starting somewhat from scratch. So...on to my question. Does it matter that I don't really know much about my cam specs?

Thanks!
Bryan
