1 If I buy a new crate engine I would keep the WARRANTY !!
2 HP cost money ! I may be wrong but how to you gain 45 hp with just a cam swap alone in this engine ? If it started with the same platform as the 430 hp engine that is a gain of 95 hp .
3 When i was younger I was told a HP would cost $100 per HP . Today's money would more like $400 per HP.
