    GM TBI to Holley sniper conversion writeup

    That’s the way I should’ve done it and I’m sure I will change it to that way eventually as that is a better setup. Edit: I should also add that one of the main reasons I didn’t do that was because the truck was carbed for a little bit in between and that is when I put the sending units in...

    Which gas is cheapest??!

    I plan on getting the truck tuned eventually and I will report back with what does for gas mileage as well. I’m not quite ready to put a bunch of money into this truck yet. All the fun stuff will come after I sell my k30 Sent from my iPhone using Tapatalk

    Which gas is cheapest??!

    2007+ Silverado questions

    So as much as I don’t wanna do it I’m going to sell my dually and upgrade to a newer truck that’s a little more reliable and does a little better on gas.

    Dually wheel questions

    These were the rims on the truck when I bought it(I know that doesn’t mean it’s right but they work and I don’t want to buy new ones) and I had to put a spacer between the tires on the back. Sent from my iPhone using Tapatalk
