    Best Fuel Tank Selector Valve Brand?

    Hello, Working on my 78 C10 and I am wondering if there is a brand of fuel tank selector valve that works longer than six months. I’ve read the threads of guys running just one tank and then using a crossover pump to fill the other. I’d like to avoid doing that or running just a single tank...

    Opinions on D70 closed knuckle front axle

    Hello all, I’m currently looking at 74 three-quarter ton square body that had a IH Dana 70 closed knuckle axle swapped in front. I know absolutely nothing about them after a little research it seems that they’re not really desirable and not much aftermarket for them if any. What are your...

I intend to use my 3+3 C30 Dually as a cruiser and going out of town mostly, with some occasional towing like a 6x10 enclosed trailer with my motorcycles. I also would like to be able to pull heavy trailers, shorter distances as I work on RVs for a...

    454 SM465 4.10 vs 3.73 vs 3.54

    I’m in the process of converting my C30 to four-wheel-drive, and will have to re gear the axles. The truck will pull our 5k-6k lbs boat 3-4 hours to the lake and used to hunt in the fall/winter. as far as highway driving 3.54 seems like the way to go but if I have to drop to 3rd at 62 mph to...

    Advice on my 57 chevy

    So I don’t think I’ll ever get to restore this car since I have so many vehicles. I don’t really want to but if I were to sell my 57 belair what would be a decent price to put it up for? My dad bought it in Wyoming in the late 70s. He resto-modded it (foot print gas pedal too) and drove it a...

    Towing heavy with my C30

    Hello all, Been doing some remodeling on the house and using my gmc to pull the dump trailer. I pulled a few stumps and some concrete/block and loaded it into my trailer, I didn’t think too much about the weight since I usually pull it with my diesel. So I get to the land fill and was just...

    500 cfm edelbrock enough?

    I ordered a GM goodwrench 350, 240 hp, for my truck. Nothing fancy, just gonna be a daily driver (for when the CC/LB DRW feels to hard to drive), should not see anything above 4500 rpm tops, half that cruising. I came across this formula, CFM = Cubic Inches x RPM x Volumetric Efficiency ÷...
