    I'm pretty sure GM has some very good prices on their Bowtie crate motors. I will say the LS1 is a great durable motor!!

    How hard would it be to swap the L18 in and what about the ls7

    Well I know the L18 is a big block motor based off of the 454, it was an option on the 2500hd and 3500hd trucks so it should fit without too much trouble. But you'll probably need a new ECU and a bunch of other stuff that's involved in a motor swap. LS7 is a small block I think so it might fit easier but again, probably gonna need a new ECU and such.
