So, I always have a hard time differentiating between a 153 and 168 tooth flexplate and the starter that matches. The bigger flexplate (168 tooth is 14″) uses the starter with offset holes, and the smaller one (153 tooth is ~12.75″) uses the starter with in-line holes. Big and small blocks all use the same two basic starters (I’m not sure about the LS engines). I really like the smaller body gear reduction Corvette/Impala LT1 starter with the small flexplate, just because that starter is so much easier to install due to light weight. :)
There’s a great thread at Chevytalk which has pictures and words and stuff. So, I’m sticking that link up here in order to prevent myself from forgetting in the future.
