Ford 331/347 Performance Short Block
TREShortBlock331/347
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 short block is the one for you! We don't recommend 4340 internals in oem blocks since the block is always the weak point. Don't hesitate to ask us about custom internal parts for your exact needs, wants, and application!
Long Blocks: There is NO EXTRA CHARGE to assemble anything else you buy from us to your short block. Please ask if you are interested in anything you don't see!
