Machine Work Required for Forced Induction

I agree with Moper 100%. One thing I would add is most foreign 4 bangers like Honda, Toyota, Lexus, etc have 5 main bearings so only one rod is isolated between main bearings. V8's have two rods between main bearings. This is huge as far as strength is concerned.

I road raced Hondas in the mid to late 80's and will tell you that the bottom ends are complete overkill from the factory, 5 mains, a main girdle, forged cranks and forged rods with only about a 2.5" stroke. The V8's need a lot more machine work to make them reliable. They are not plug and play with power adders that make some decent HP.
