Which cam to go with? Stock heads bottom end...

There's a pretty big difference between AFR 185's and GT-40 heads. Your head selection will ultimately determine your cam selection, but most people will probably recommend a custom camshaft. Also, you said you recieved pedestal mount rockers. I'm not sure if AFR makes heads that use pedestal rockers (someone know for sure?). I would just add the 1.7's now, which should give you a little more power. Why did you buy the Edelbrock RPM? Are you planning on more cubes, a power adder, or higher revs later on? I've heard from many people that the RPM will cause you to lose some low end torque on a lightly modded engine. It's mainly designed for a higher RPM powerband. I hope I didn't get too far off topic, I just wanted to help you with your whole combination.

imo if you planned on getting a blower you should have bought the RPM II just for the fact that it moves more air and thats what your trying to do. i would defineltely go with the 185s. give ed curtis a call and have him grind you a cam. well worth the money spent. if you do go with an off the shelf, id do searchesto see what other people are using and what kinda results they are getting.
