I must have a vacuum leak. I have a 110 lobe center 264/274 cam in my 250, so the vacuum should be a little lower than usual but mine is LOW! How do I figure out where it is coming from? Thanks.

When you find the leak, the engine will rev up.

The procedures I have read on this site say to tighten until the pushrods can't be rotated between your fingers and then tighten an additional amount. I did that on a 289 years ago and they were too tight. I readjusted again but the second time I only tightened until the end play was gone but the pushrod could still be spun and then the additional amount thinking that I misinterpreted the procedure and that seemed to do the trick
