Dyno Numbers vs Cam Selection
I've been playing around with Desktop Dyno (an engine simulation program). I wish I had purchased this program prior to selecting the cam for my engine. I'm running a 428, 10.25 compression, Edelbrock heads and a dual plane manifold. Below (if I did it right) is a table showing the hp and torque of some of the cams for this engine. My engine is running cam #9. That's good for about 458hp@5500 and 493ft-lbs@4000. Looks like there are lots of other hydraulic cams I could have selected that might have been a bit better. But the ones that are really interesting are cams 22 and 24. 22 is a solid-roller that should pump out 502hp@5500 and 573ft-lbs@3000. 24 is a hydraulic roller that should be good for about 526hp@6000 and 534ft-lbs@4500. Wow! Is anyone else running a roller in their FE? Besides cost, are there any pitfalls I should be aware of? Of course, if I were to go with the hydraulic roller, I'd need the cam, lifters, new valve springs, keepers, etc and maybe pushrods. That's a lot of bucks but it shouldn't be too tough to do. Any words of wisdom?
