I have been doing research. I live at high elevation and lose 1/3rd of my HP. I have decided to do a gen V swap. I am running a fully built rig with PR60/80 and 40s. The 8L90 will help a bunch with the mountains. Right now it is dreadful. I am debating between three engines. LT4, L86, and L86 w/ Texas Speed cam swap. My budget is flexible, but not infinite. Is the LT4 HP overkill even at altitude? What is a good price for a low mileage LT4 and L86? Is the Atlas 4 worth the extra money over a 2?
