On a different list I was involved in a thread about the length of SBC intake manifold bolts. According to David Vizard they're 1.25" long but a friend of mine learned the hard way that some aftermarket intakes aren't as thick around the bolt holes, and that can lead to pushrod interference:
http://www.classic-fbody.com/~joemac/hallofshame.html Last night I compared a 1972 iron intake, an Edelbrock Performer #2101, and a Performer RPM #7101. Using a micrometer I measured the thickness of the metal at each of the 12 bolt holes: OEM: .55-.58" thick #2101: .43-.48" thick #7101: .37-.42" thick Anyone considering the replacement of a stock iron intake with an aftermarket aluminum intake would be wise the measure the material thickness, visually check for bolt-to-pushrod interference (center 2 bolt holes on each side), or both...

PS The #7101 is for sale - email me at [EMAIL PROTECTED] for particulars. ----------------------------------------------------- To Unsubscribe please visit www.chevelles.net/list.html To start a new topic, send mail to: [EMAIL PROTECTED]
