Step by step total timing instructions

Hi guys, im relatively new to this stuff and need some help. I helped my dad build a 360 stroker (408) before he passed away suddenly last year. He was the brains of the op and i need some help!

Im running 10:1 compression, rev n nator distributor/box, eddy 650 carb, 484 camshaft. Ive never set the timing on any vehicle and im on my own so i need in depth, step by step instructions on how to set total. Ive got it idling pretty good but just did that by sound. When i drive it, the engine starts bogging/backfiring around 2500 rpms, im thinking its bc i i don't have proper total timing as there are no duel delivery issues (6psi getting to carb)

Thanks all for help!
