Correct Aftermarket Starter?
I'm buying the last few things I need from Summit, and I was planning on ordering a Summit Brand Mini Protorque Starter, but I just wanted to be sure this was the correct one.
Summit Protorque Mini Starter
It says for the Inline Bolt Pattern, which I believe is what I have. This is what the starter pad on my block looks like...

So this will work out for me right?

Your block is drilled for both starter bolt patterns- straight and staggered (like many GM blocks are). So you need the correct one for your flexplate/flywheel. If your is the 153 tooth you need the straight bolt pattern. If it's the larger 168 tooth you need a staggered bolt pattern starter.

Starter says it will work for both, but only had inline bolt pattern, so hopefully I'll be fine
Thanks!
Thanks!
