[QUOTE="TBItoy, post: 761448, member: 1384"] Power is power. Driving style will determine if your axles live. Doing a full engine swap in a full body-multi passenger wheelin vehicle, an "LS" motor is really the only thing that makes sense economically. I'd find an aluminum block "LS" motor, just for the weight savings, probably a truck 5.3 and swap it with the 4L60e. Just leave the motor stock. I'm pretty sure that all the "Trailblazer" variants that had 5.3s (a lot of the long wheel base trailblazers, most of the Buicks and GMCs, etc) had aluminum block motors. The only other thing I think I would entertain would be turbo'ing the stock 4cyl. That may give it just the little extra bump you need [/QUOTE]
