V8ZRACER260Z Posted December 28, 2007 Share Posted December 28, 2007 What valve springs should my friend use? He has a 302 with Vic Jr heads with 205 intake & 160 exhaust valve, his cam choice is a 670 lift solid roller by comp cams. this is for a Mustang bracket racer and he only drag races it.

blueovalz Posted December 28, 2007 Share Posted December 28, 2007 I would tell your friend to check out the Comp Cams web site. They provide the recommended spring and its specs. The link below show cams, followed by recommended components for those cams. http://www.compcams.com/technical/Catalogs/106-07/64-71_230.pdf Quote Link to comment Share on other sites More sharing options...
