OK Here is the deal, I did a cam change and like and idiot some how messed up my balancer so I replaced it with one the same size and my timing cover has the pointer on the driver side of cover but then I noticed that my old balancer had two marks and I could not tell if some one put the second mark on it or if it is made that way but with the new balancer on it it will not run near the timing tab. Someone advised me that I had the wrong balancer and timing cover cobination and that 0 degrees would now be top and dead center of the engine. If this is true how do I correct the problem to ensure I set proper timing. Also on a pretty much stock 350 what do you recommend setting timing at and can you set total advance timing with a basic timing light. Also what about advance I am confused about it should it stay or go. When I bought the car it had stock curves in distributor but he said it had the soft springs from a curve kit. Does that sound right.

Whitlightning-- i think the place to start would be to set you motor to top dead center(make sure your at top dead center). This should be your 0 degrees. If you have a degree wheel put it on the balancer and put a mark at 0 and then find the degree number you need and mark it with a marker. Romove all other marks and you shoud be set. If you do not have a degree wheel then find out where your balancer is at --at top dead center(example if its at the 6 degree mark) then ad 6 degrees to the wanted degree and you should have it. It should be close. We have done this and it has put us right up there with the big boys.

Example-- top dead center is on 6 degrees--and you want 36 degrees then set it to 42 degrees on wheel and you will be pretty close.. The balancer degree wheel is the best choice though..
With no advance I set timing at around 3000 rpm. Set your rpm to 3000 and set your timing- It should do gr888 from there. Just remember I am from the old school--lol but it has worked well for us.
Some racers will probably shutter and have twitches from my post--lol

Oh yes just my 2 cents worth but if your running dirt I would do away with the advance and lock it in. Wheels

yes i believe if you bring top dead center up on #1 cyl then that should be your 0 degrees. Then you can go from there. Make your marks accordingly and you should be close. Wheels

Where would you recommend setting the timing on a 400 motor on methanol? 400 oem block, steel Dart 23deg heads. Our motor builder said about 38deg sounds right but this is his first alcohol motor. Any suggestions?

Timing would depend on the whole combination but i think somehwere in the 34-36 range would be good. We used to run that same motor and set it at 34. Dyno proved this made most HP but there was really no difference between33-36... more than that and power started to drop.

A good starting place is 36 degrees.. I think you would be very happy with that..
