    Agreed. I pulled my hair out over that ground on the bottom of the block. Called Casey "Man why won't this thing fire? - Crawl under the truck, check this ground, call me back in 5 minutes I want to hear it running" done.

    yes Sir! I will posting a new thread in soon, that will have all my parts i had to buy, modifications, and changes for this conversion. For people that are interested, because it was a slight pain and it just doesnt drop in and work. But worth it!

    There's already quite a few threads on the swap. You didn't break any new ground.

    Yea I can put one up. Right now we are swapping intake manifolds on it. I have a video but it shows us starting the engine and it catching fire haha! there was a small leak in the fitting on fuel rail line. No damage luckily.
