STR Posted July 25, 2003 Report Posted July 25, 2003 how much vacuum does a stock 3.4dohc have? right now i'm at 15 inHg @ idle. i know this is low due to the RSM ported intake/throtle body. i was just wondering if anyone here knew the stock readings. thanks Quote
Robby1870 Posted July 25, 2003 Report Posted July 25, 2003 I would think something near 20in of Hg at idle would be close to correct Robby Quote
