Anyone had experience with a 94 bronco 351 engine? i am looking at buying a wrecked bronco with a running 351. I think those engines had roller cams? How are they for boring and stroking? Plan on keeping the EFI system.
If the block is an F4TE casting, it's a roller block. Regardless of whether it's got a roller cam or not. (the rollers were phased in starting in 94) Pulling and checking a single pushrod will tell you if it's got a roller cam. The roller 351W pushrods are about 7.5" long.
