A lot of bravery. Everything I've heard about them is that they are grenades.

Re: 8.1 vortec?
They just about bolt in from the threads I have read.
It wouldn't be my first choice as they are sort of un-loved, but it is a solid motor. Plus I feel it is better then the 6.0 for the 2500/3500HD's. When I was considering a Big block I was thinking of doing the vortec head swap with a decent cam. |

Re: 8.1 vortec?
Almost everything you ever wanted to know about an 8.1L in one thread. I got tired of the numerous PM’s and emails and started a dedicated thread on a reliable forum
