i got the single bolt billet 9 way timing set off 440 source. hoping it's not completely garbage for 130 bucks. saw good things about it online though. if i can't get it in spec with the 9 adjustments ive probably got bigger problems ha. i probably could've gotten by with the comp cams timing set but id like to get away from comp stuff after my break in fail and my buddies cam lobes going flat. i cant say for him but mine was treated well and broke in everything by spec and after only 15 minutes of break in it wore 3/16 inch grooves in my comp lifters with a comp cam. did a complete rebuild after that and used isky cam and crower lifters and it broke in good. we will see how the lifters look with around 500 miles on them when i pull the intake tomorrow. thinking about my cam being smoked again gives me the same feeling i got on christmas eve as a kid.. just hoping i dont get any charcoal this time around lol.
