LoBelly,
I converted my auto engine to manual so had to purchase a new flywheel. I got a 157 tooth fly wheel as I am running a T5 and this requires the smaller wheel. Make sure you get the balancing factor right as well.
This is from the Ford Racing Catalog:
Did you know…
1968-80 302 engines were built with a 28-ounce imbalance factor.
1981-01 302 engines were built with a 50-ounce imbalance factor.
1969-97 351W engines were built with a 28-ounce imbalance factor.
1970-74 351C engines were built with a 28-ounce imbalance factor.
NOTE: Severe engine damage will result if you use the wrong flywheel or damper on your engine.
Download the catalog from
Ford Racing Parts . This has more info that will help you choose, look at page 128.
Cheers,
Dan
