> I wouldnt say much more expensive. There are thousands of trucks built every year and these motors are much more plentiful than LT1s and Vortecs. The low CR makes it even better cause you can run 87 now and 20psi boost later. The LT1 is still a great engine but its becoming less practical every day

lt1 does not have low compression, hence why it went to a reverse cooling system in hopes to run more compression, i believe its 10:1 cr
