OK. I want to put a junkyard mini-starter in my 350 with a TH350 and 153 tooth flywheel. As I understand it: Mounting bolts should be straight across, not staggered. The best (higher torque) starter is off of a 4.3. The best starter is off of a Vortec engine. I need the bolts (shorter) with the starter. I need to get a starter that has 9 teeth on the drive gear. It should be found on a '95 or newer vehicle. How do I tell the year? How do I know if it's a Vortec engine? How can I tell if it's a 4.3? Is any of this correct?
