is this a fair price to swap out my engine?

Also, is there an advantage of using a 153 or 168 tooth flywheel, one over the other? It seems you can use either, but just have to buy the correct starter for whichever you choose.


Any advice on this is appreciated!

It looks like a short one, and if so the alternator would be on the driver's side.

The 168, being a larger diameter gear, would provide more leverage to turn the engine over and logically would turn the engine slower.

I would get the 153 tooth due to the low compression engine you are installing and get a gear reduction mini starter.

You are right, only need to get right starter to match the flywheel (flexplate).
