need help with case study project

[Matt167]

in my auto class I'm doing a case study project on automotive starters, so me and my group are trying to create a scnerio involving an engine swap of 2 SBC's, using the 2 diffrent SBC flywheels, the 153 tooth and 168 tooth, so 1 of the motors would have the 153 tooth, the other a 168 tooth, where the installer used the same starter ( obviously grinding up the flywheel ). but what is 1 vehicle with a 168 tooth, and 1 with a 153 tooth?, so I can say the motor was swapped was this, to this.

You could say the flex plate with the 168 tooth count external balance is a 400 sbc in a 1979 Chevy 1/2 ton pick-up.
The 153 tooth count single pattern internal balance flexplate can be out of any Chevy car 262-350 in size from 1955- 1985.

I have a 78 vet 350 and it uses the 168. So does my 70 350 C10

dont forget the heat shield either... the starter tends to not crank when the engine is hot and the heat shield is missing

You will notice I said external balance when I was talking about the 168 tooth flexplate.
I also said internal balance when I was talking about the 153 tooth flexplate.
Both of your 350's are internally balanced engines.
