At least go with eagle " I " beam rods. Bottom end on these 427's are CRITICAL. There is a bunch of side load on the cylinder walls. The 351 Windsor blocks can be bored up to 80 over, so there is alot of meat in the block left after going 40 over. 40 over with the scat 4.17 crank puts you at a true 427 cubes, 30 over is about 425 cubes. My Scat crank will be Cryogenically treated, which is kind of like forging at a molecular level. So, at least I beam rods, good crank and a stud girdle should keep you from grenading the motor. I would much rather burn a piston than sling a rod through the side of the block! Just remember, you get what you pay for. Scat has proved to be some good ****, but go with Eagle for no doubts.
