Ford 331/347 Performance Short Block - TREperformance.com
Ford 331/347 Performance Short Block
Our 331/347 Performance Short Block is the perfect short block for your high 9 to low 11 second cars. This bottom end is balanced to 28oz and ready for all the abuse the block can handle. Whether you are planning a high rpm n/a setup, a lot of nitrous, or lots of boost, this shor tblock is the one for you! We don't have a 4340 crank/rod roller 302 shortblock because ITS A WASTE OF YOUR MONEY! We only offer the 4340 stuff for the 4 bolt Dart block and sportsman blocks since the stock roller block is always the weak point regardless of the rotating assembly inside of it. This shortblock is designed without the wristpin in the oil groove for the ultimate in reliability. Don't hesitate to ask us about custom internal parts for your exact needs, wants, and application!
