OK, I have an LS swapped built 85 C10 and was debating on pulling that motor using the 440 HP LS1 built by thompson motorsports or upping my game by either buying a 454LSX (crate motor) from performance chevrolet or a Blueprint Engines 427 LS? Both have 625 HP. The blueprint engines motor has a better warranty. Not sure what direction to go? The 370 LS1 is fun but I really love that holly sh*t factor the bigger LS will provide. Most likely i will use the 4l80E transmission. I am in the planning stages now but eventually i will make this happen. Both the 427LS BP motor and the 454ls chevy crate are close in price. ??
