good to know, i had this motor built probably 4 years ago so im foggy on the details but the numbers i remember about my cam is 484 and 284. which i know is the lift and the duration and i just mildly understand what those numbers mean. what is your expert opinion on that cam with a mild built 360, with the j heads rebuilt, airgap manifold and demon carb, with headers and hydraulic valve train. sound like a decent match? id like to upgrade to a solid lifter roller cam and lifter set up some day probably when i do the stroker but for now im wondering if that cam is about right. although this is a street car, its my race car so im always looking for improvements that i can afford.
