There is some signifigant fabbing to make centermount work. I don't have any pictures off the old truck but maybe I can take some of my c1500 when it goes back together.
This is all stock other than turbo and fuel system. My truck gets the centermount setup. We had it on one of our trucks with a 71mm turbo and had fun hurting feelings . Wish we had dynoed that thing because it had no problem running alongside 600+ hp trucks and soundly beating anything less.
The dyno was having issues that day and only read power to the mid 3k rpms but we are fueling to 5k. Dyno operator felt bad and said he feels like it was reading low by 25 to 50hp. Hard to say. This is a baseline so we have a solid starting point
We made a few of the parts to convert them. Did at least 2 pumps, the one puts out 220 cc's of fuel and it has compound turbos on. It's a lot of fun to drive
The ones I saw that were hitting the pistons were only recessed at .30 thousandths if I remember correctly It's been a while since I worked on one the newer heads so I'm not 100 percent sure on the numbers anymore. And yes it was an issue with the intake valve opening prematurely. The worst head...
