260ZRED Posted March 13, 2004 Share Posted March 13, 2004 Is anybody 100% sure on this one...? I have ordered and received a 6.75 inch harmonic dampner for my 350 (or so I thought) but on the box it says "for use with 400sbc's"... Can I still use it, or is the balancing needed totally different from a 350?? thanks. Quote Link to comment Share on other sites More sharing options...
labrat Posted March 13, 2004 Share Posted March 13, 2004 Balance is off. Needs a neutral balance dampnerand it sounds like you got an externally balanced dampner. One side should be 28 oz. or so heavier than the other, throwing a 350 way off balance. Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted March 13, 2004 Share Posted March 13, 2004 Definitely NOT! Quote Link to comment Share on other sites More sharing options...
jbeech Posted March 16, 2004 Share Posted March 16, 2004 No. 400sbc engines are externally balanced. Sorry, you got the wrong part, don't try it. Quote Link to comment Share on other sites More sharing options...
