Sbc Vacuum Gauge Bouncing at Gilbert Strothers blog

Sbc Vacuum Gauge Bouncing. i look at the vacuum gauge and it is bouncing furiously. i have a 350 sbc fresh build with 670 holley street avenger, crane hydraullic roller cam with 222/230 @ 50. We’ve seen this topic covered before, but it’s information worth repeating, keeping—and even bookmarking. a hot cam usually results in a lower vacuum reading than a stock cam but it should still be relatively stable at that. After stopping, the vacuum is bouncing between (roughly) 10. the vacuum gauge tells me its a valve train problem, valve too tight, burnt valve,etc. If it is a head gasket you would. has developed a rapidly fluctuating vacuum gauge needle between 19 and 21, at idle speeds upto around 1000. any time you see a rapidly bouncing gauge the first place to look is for a leaking intake valve for whatever reason.
