Not a SBC guy, but as I understand it if you were bolted to the staggered holes you should have a 168 tooth flywheel as opposed to 153, but you need to know for sure. If you look at Summit's listing, it appears that you can buy any combination you want - this page (attached) shows 350V8, 168 tooth, in-line mount - http://www.summitracing.com/search/p...pattern/inline
You can pick up a ton of info on the history, and the changes in bolt patterns over the years if you read through this thread - look in particular about 10 or 11 posts down to a guy named DZAuto's post - 153 vs 168 tooth starter - ChevyTalk --The Social Network for Chevy Fans

Or, you can extract the bolt.... Welcome to CHR, by the way!
