301 Timing

[79g-body]

O.K. fellas heres the deal. I checked the timing and with the vacuum taken off of the dist. It reads about 20 deg off. Instead of being 12 deg below TDC is't about 12 deg Above TDC.....

What do you think.....Also someone told me that some cars had two marks on the Balancer. I have not checked yet...

there is only one mark on stock balancers....have you adjusted the timing yet and if so how does it run?.......you can also check the timing with a vaccum gage...

I adjusted the timing last night and what a change. Runs pretty good but at 3/4 to full throttle there is a loud bellowing sound coming from the carb. Like it's really sucking too much air or something. The car doesn't die or anything. But it really doesn't accelerate very well once I hear that noise. I am thinking about checking the timing chain and make sure that it is good.

make sure the jets in your 2 secondary barrels are providing fuel...
