Ive had good luck with 16 initial and between 34 and 38 total. That cam is great for a daily driver, but not that great for 1/4 mile times. thats smaller than what I run in my 3/4 ton daily driver! the intake is also old technology, and wasnt ever that great, can be ok with some portwork. but a good dual plane such as RPM would be better.
If it was me I wold keep the converter for now, recurve the distributor, change to 6500 pill, and go test it. If you want to change parts, I would start off with a performer rpm, and a cam such as the voodoo 268 from lunati.
