drop your little know it all attitude.I said it DEPENDS on what QUALITY your after… LMR 408 or junkyard GM 4.8… Put either motor in a car with more real world type situations and see how each does on 66 passes smartass…to some people pice of mind is more important then $/“budget builds”…so is a shops rep wrather then which junkyard they went to. 4k drew…I’m sure after all the fab is said and done to put that 4.8 turbo setup in a car it’s just a tad bit more money. I can build the Sam racing 1064hp n/a motor out of a fucking 4.8 for half the cost of what that setup cost too
