So after all the work I did I am noticing that my SBC vacuum will only go up to 10 at idle. That will be consider a problem I guess. I cant find any leaks but my guess is the location where I have the vacuum gauge connected. It is at the front lower port of my Holley 650. Even if I have a choppy cam it should not be that low. It is just supposed to jump up and down by maybe increments of 5.
This could also be the reason for softer gear changes on my newly rebuilt TH350 I guess.
Any body has an opinion about this issue?
