Default 157 tooth vs 164 tooth flywheel

I just purchased a 1972 351w engine. It came out of a car with an automatic transmission. I will be installing it with a 4 speed toploader. I am looking for a bellhousing and flywheel and came across the two different sizes. What are the (other than obvious) differences. Is there an advantage to one or the other? Thanks.

Using the 164-tooth flywheel you can run an 11" clutch. Besides the bellhousing and flywheel you'll also need a new block separator plate for the larger bell.

157 tooth flywheel = 10.5" clutch , 164 tooth flywheel = 11" clutch , 157 riverside avenue = REO !

What about the flywheel balance. I see some are 23 oz, some 50oz.

All 351s require the 28.8 oz-inch imbalance flywheel or flexplate.

50oz. is for the newer mid 80's to mid 90's 302HO AKA 5.0.
