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. This bottom end is balanced to 28oz and like all of our short blocks, is professionally assembled, machined, and has all new parts installed. We also will paint the block your color of choice, free of charge! 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!
