im gonna be building a 393 and was wondering fow good stock 93 windsor rods are. they came out of a truck motor. im probably gonna be shootin for around 500hp at the flywheel. i might also be using a 351 mexican block thats early 70's. wondering if anyoone knew what kind of advantages ill have with the block. i know theyre thicker but i didnt know if there would be clearance problems. ive got a buddy thats a early ford guru and he never even heard of a mexican 351. but the kid assures me that thats what it is.
