Big-blocks like about the same timing as smal blocks. Some big-blocks prefer 38 dgr due to crappy chambers.

I prefer to keep total timing below 50 degrees though. Might want to switch over to a 10 or 12 dgr vacuum can.

i did pull the timing back to 50 deg and i like the way it runs and sounds.... don't know to much about the chambers but the head casting #3917215, is what i have noted in one of my books... the vacuum can i have is B-26,.. 16@11-13hg ... 16 @ the crank.... i have very good vacuum at idle,14hg and 23hg at cruz... thinking maybe i should try the B-1 vacuum can, it's all in at 16-18hg.....

THANKS!
Mike
