How do you initially time a BB before startup?

you should not simply assume your balancer marks and pointer are correct. use a positive stop method to identify top dead center on the balancer and pointer as they exist. then measure the circumfrence of the balancer using a narrow tape, divide that number by 360 and thats the radial distance per degree...multiply that number by the number of degrees you want marks for and mark ( or confirm) your balancer appropriately. they sell timing tapes for this at your local speed shop but knowing your tdc mark and pointer are correct is critical at this point.

simplest method is if it cough or pops or doesnt start, you arent even close. loosen it up, turn the dist. a little, try and start again. after a couple tries the motor will fire right up, get your timing light out and set it. 5 minutes.....

This is going to be determined by where it runs best on the dyno. Probably somewhere between 32* and 38*. Setting at 8* for intiatially starting it will be fine. The total timing at wot or actually above 3000rpm's is whats going to be important. That's where they will be determining it at. Where it ends up being during idleing isn't that critical. If it is too far off at idle then they will make a correction in the distributor advance curve.

Piston stop and timing tape is what I used when mine went back together. It's really the only way to know for sure that you are shooting the right number. And plus the timing tape shows up a lot better when shooting total.

i know its a new concept for you to do the basics correctly first rather than fix the failures later but ponder on it and it some and will come to you, i'm sure.

All your information is very helpful and now I completely understand exactly what to do. I really appreciate all your help and I will post dyno numbers and try to get a picture of the sheet up. Should be within 2 weeks. Thanks again everyone!

not as confused as he would be if it has a mismatched front cover pointer and balancer and the marks are wrong by 20 degrees...
