Thread: LH6 vs L76

  1. #1

    Default LH6 vs L76

    Both engines have the VVT and AFM and both are small blocks. However, one is the 5.3 and the other is the 6.0. So my question is: What exactly is the mechanical difference between these two?

    To Be Completed (Eventually):

    Most "family" motors are just bore and stroke. The 3X00 series is the same, a 3.1, 3.4, and 3.8 are all the same sized block, just different bore and stroke, and in the case of the 3.8 heavier internals being that it easier to make one block a SC then the next one on the line NA, instead of having two seperate lines.

    the block is different to accommodate the bigger bore
