i just changed out cams and whole valve train on my car but it doesnt lope any harder... i upgraded from a little bitty edlbroke pepboys cam to a solid roller lunati .502"/290 cam... any reasons why its not loping good?? everythings fine with it i was just loking forward to a good lope and was wondering why i wasnt getting it with that cam

did you upgrade anything else with the cam? or is it all stock?

With exaust headers, heads, and an intake you will get the effect you desire. Also, make sure your valve springs can handle the lift of the cam, that's a pretty big lift and some springs may bind.

Do you know the lobe seperation angle? I'd say 109 up won't lope much. Add the intake centerline and the exhaust centerline, divide by 2, see what you get?

What RPM do you have the car idling at?

I have a solid roller in a chevelle thats the same way, 242 duration @.50 .607 lift w/ 1.6 rockers..but alot of its in the lash, once I finaly figured how to set them right, its got a nice rumble to it..I used the crane method..

lobe separations 112.. must be it.... yeah everything was upgraded with the cam.. holley aluminum heads, 2.02/1.94 valve the tri spring valves all the goodies.. would the cam timing effect it any??

that cam doesn't have a ton of lift or duration, thats probably why it has no lope. it should sound okay though. idle it around 800 for the most"lope"
