you have a bronco II too! im still in the process of convincing my old man to hand down his. he has an 84 bronco II eddie bauer edition with a carbed 2.8 and 4 spd with od. the brakes are shot on it and its almost a box of rust... but now that i think about it, i heard that, just never thought anything of it. i know the chevy 350 doesnt pop like that, my buddys got one with some really cheap mufflers on, no cat, 3' piping and it doesnt do it what so ever. but i also know the 360 does it, but im not sure about the 318... im sure if you get the right muffler, you could make it sound nice and loose the popping sound? maybe thats all it is? or maybe smaller piping to increase backpressure?

Would engines that have automatics also do this or is it only manuals because ive never seemed to notice it unless the magnums do it
and My step dad used to have a 93-94 Ford Ranger with a manual trans that did that, though he traded it in either in late 08 or early 09 for a 2002 Dakota though while riding with him ive never noticed either though his also has an automatic

when your driving, try shifting the lever to 2nd or 1st, youll hear it. mine does it when i just rev it up when its in park or neutral. im starting to think that this is just a multi-port issue, cuz my TBI 3.9 in my other truck doesnt do it, my buddies 350 is TBI and it doesnt do it.... i really wanna figure out how to change this... i HATE that sound!!

I did that today but it wasnt for that reason, but mine never did that so mabey that possibly has to do with direct fuel injection (or whatever the hell they call the kind that the magnums have)
