ok, I've got to ask??
WHY DO YOU WANT A NEARLY STOCK ENGINE to RUN LIKE CRAP AT IDLE , with a cam that has the kind of timing that will kill off a good deal of low rpm drive-ability.
yes its easily done by over caming the engine , theres even cams designed strictly to produce that lope in the idle.
but consider the end result is very likely too be a car/truck with LESS response that the current cam
that "LOPE in the idle is mostly the result of OVERLAP in the cam timing causing low rpm reversion pulses and extended and delayed exhaust valve timing, combined they cause the engine to run far less efficiently until the rpms increase enough to cause the combined inertia to smooth the idle as the rpms increase, yes that lope in the exhaust note,is a SIDE EFFECT on a high compression race cars engine,and it can be semi duplicated in a low compression engine,(the sound)by a cam thats designed to produce power in the upper rpm ranges with increased cylinder scavenging efficiency, but it does nothing good for performance on a stock engine, that can,t effectively use the potential for increased flow rates well over 5000rpm
thats kind of like the fat UN-cordinaded kid in the third grade, walking around with a sign on his tee-shirt that says
"I CAN KICK YOUR ASS! JUST TRY ME!"
its unlikely to be beneficial in the long run!
here it is if your certain your goal is only to have a lope in the idle, and loose a good deal of off idle power

if you want to build a kick butt engine that actually will add significant performance we can help you design and build one, but Id suggest avoiding over caming an engine, especially when the net result will likely be a loss of both money and performance
