vacuum help!!!
Hi All,
I have a 400 with a comp 268h grind and the 9 to 1 pistons.
my vac. gauge is very erratic-between 20 and 12.needle moving very rapidly. and how much vacuum is supposed to be at your valve cover breather? mine is really sucking. I'll check for leaks while waiting for a reply.
thanks , any info would be really helpful.
