Today I put 65H (not sure what the H is for) jets in my center and then drove it, surging is improved and overall drivibility is back.

I was talking to a friend of mine today about my timing and he looked in his Mopar Performance big and it said that they recommended as much as 50* total timing, initial, mechanical and vacuum. The reason I was discussing it with him is setting mine by a vacuum gauge it came up with 22* which had the best idle and just felt right. My concern was that it gave me 50*+ total timing, which I wasn't confortable with so I backed it down to 40* total and left it there, performance is good there but I have to run more idle than I want (4 speed car). Tomorrow I am gonna run it up to 46* total as well as make the few other adjustments to see where that gets me. Like my float levels, I got some more clear sites this afternoon so I can try that again. Maybe I can get back on track and do Tom's set up from start to finish.

Any thoughts on where I am?

Has anyone run 50* total with no ill effects on a LA engine?
