UTG -The Mighty 318

And you can compare modern engines, the main advancements allow performance and low speed driveability eg.. OD, Multiple displacements, variable timing. None of those allow more power than what we hot rodders can do just we got to compromise more. New LS and Hemi are great cause there heads flow as much as race engines stock which just leaves cam change to get the power out of them, but throw on similar heads on 273/318/340/360 and you can make the same power.
