If you are planning on adjusting your timing make sure you check your harmonic balancer berfore u do anything. If it looks worn and has rubber sticking out replace it. I didnt check mine and wound up setting the base timing and with a timing light i "set it to 12 adv." but since my balancer was shot which i noticed a month and a half later with detonation and never being able to get it back where it was i replaced the balancer and seen my timing was at 28* advanced. Replaced balancer reset timing to 12* and now its perfect. Im lucky my motor didnt blow from all the detonation/ping. Be careful. Dont make the same mistake i did. One more thing. If you buy the proffessional products balancer from 5.0 rest u will have to find or buy new bolts for the pulley. The stock ones are too short by a long shot.
Did you buy it with the adaptor? What timing marks did you use? It looks like the ones on the front need to be used. I am asking because I am just now putting my motor back together and am using a Prof. Prod. SFI race balancer.
you can go more than 12 you know. when i had my car tuned when it was close to stock i had it set at 15 with 93 octane. when i modded it and did the 347 stroker to try and lean it out it was set at 19
