Thanks F-Bird'88, I'm going to check the advanced weights but since the whole distributor is new I don't think it would be warped; then again you never know.
I am more convinced now that the pro-billet (made in US of A) is the way to go. I read an article about a week ago where MSD was indicating their streetfire was chinese made and was their attempt to stay in the market they were losing to low cost alternatives. The way I read it they were pretty much apologizing for the lower quality of the unit.
Personally I don't like to scrimpt on certain things and the streetfire was a mistake so I'm going to correct that with a pro-billet. I already have a friend who will take the streetfire off my hands for a stock application and he will give me 90% of the units value so that helps.
I have multiple threads but they are not related. One is for mechanical advance (this one), one if for holley setup - transfer slot and one is for Holley setup - Choke. I guess you could say they were all related to engine tuning but I personally like to keep subjects separate as change-of-topic questions get lost in the discussion sometimes.
As for Cam shaft and torque converter specs; they are:
Cam: 450 lift, 224 duration, 206 lobe centre
Torque converter: new 1500 stall unit from GM - 2 years old now. (long story, had a 2500 in there and it went bye-bye when the transmission fried and now I have a rebuilt thm-375 tranny with 1500 staff as recommended by the tranny shop).
Thanks for the feedback, I guess my next step in this thread is to get the HEI Pro-Billet and go from there. I'll update how that goes when it comes in.
Cheers
