Flatheads might be around longer. All that electronic and plastic has time limit less then metal. But I could enjoy 800hp and not complain! |

Re: timing advance how much is to much
While electronic engine management systems are superior they're more complicated with many parts prone to intermittent failure making them a pain to diagnose. With a flathead you can pretty much see what is or is not working. Even when it is not you can still make it home many times.
Back to the chevy distributor. As Charlies NY explained to me once, it is all about the ping. You can run a few more degrees total advance and when you open the throttle the vacuum drops out giving you enough retard to avoid pinging.

Re: timing advance how much is to much
Not only is the total advance a little low in degrees, it is coming in late isn't it? You would want total in around 2000-2400 rpms.

Re: timing advance how much is to much
yes and done by educated guess work and checked with only a tacho and a advance check timing light not a bad effort considering the parts sent where for a different dissy not a yh series but its better than what some YOYO in the usa bolted together as i said before looks cool pity it runs like shit yes ron not the perfect curve achived but better and all advice was taken into consideration AGAIN thanks to all who took the time to reply
