Well now I am pretty much completely freaked out went and got the rhodes liftersand they say it knocks 10-15 degrees off all the stats soooo.....224/230 duratoin at .050 should drop to214/220..or possibly even 209/215 and the abdc @61 should drop to 51 to 46 degrees I also have a 3 key way timing roller chain should i move the key way to retarded or advanced to help with retarding the abdc of 61 degrees on the intake. I read a article that sayes moving the timing crank gear forward and backwards helps low or high depending on which position?This cam nonsence is turnin a fun first time build into a headache!!!! Help Southerner!!!lol
