Cam & engine gurus gtf in her meow!

At this level of engine I wouldn't even recommend the RPM airgap. Edelbrock performer 318/360 gasket matched to 340-360 port size is a better choice, or a Weiand stealth (it's 318 port size, but it's nearly identical to the old Edelbrock LD4B intake), or factory iron non EGR four barrel intake. If I were bound and intent on camming it up for a little extra sound, I wouldn't run any more than this grind, COMP Cams Specialty Camshafts 20-306-4 and I would install it at 4 degrees advanced, too boot. The rump rump chop chop idle just isn't worth it to have a vehicle that can't even safely merge into traffic.
