Re: 472 Cadillac engine?
The only issue the 472/500 motors had is in the oiling system-the wide main bearings soak up a lot of heat and tend to score a bit by the time you get to 60K and up.....but, a quality overhaul using Clevite Tri-Metal bearings will help a lot-I would recommend lightening up the stock crank while at the machine shop and paying extra for balancing the rotating assembly to +/- 3 grams.....that'll help ensure the heavy rotating assembly won't tear up the bearings much.....obviously synthetic oil wasn't a luxury those old Caddy motors originally could have taken advantage of but they can now-that too will help extend its life. For the record, in 1970 the 500 motors were rated the highest in stock form-375 HP and 500 FT!
