    Good rear gears

    That's what I thought too. I had it floored and surprised it didn't detonate at that time

    Good rear gears

    I'll try the online calculator I got off this site to figure out what I have. Unfortunately right now I pushed the engine past it's limit and threw a rod so the replacement engine is toast. It wasn't a rebuild, just a used drop in.

    Good rear gears

    Good Afternoon members. Just got my truck back with the "new" Vortec 350. I want to do some long distance driving with it but was told it's geared too low. It's an 84 C2500 with the TH400. I don't know what are in it now, but want to change them out in the next few months. I'm just doing in town...

    Auto shifter bushing

    I found out the bushing that is on the shifter to column rod is missing. Can someone post a pic of what it looks like for me please? My truck is at the shop locked up. It's an 84 Sierra with the TH400. Apparently the linkage was a little bent from the PO when it was a farm truck. Thanks and...

    Exhaust downpopes

    Thanks Ricko1966. The Y pipe that was on it was homemade and the left side wouldn't allow me to utilize all 3 gears of my trans as the shift linkage was hitting it so I bought the new kit. I appreciate the info. Thanks again

    Exhaust downpopes

    I bought what I thought was a complete, minus mufflers exhaust system through Jegs a couple years ago, but it doesn't have any downpipes. It's a standard 2.5" kit. No one carries just the downpipes, and mine were homemade. Does anyone know who I can get just the 2 stock downpipes through? My...

    Reinforcing Door Striker

    I used a piece of blue pex tubing on my truck. Put it on both several years ago and no rattle and the doors close perfectly. I have access to a bunch of the tubing at the railroad where I work so keep 3 2 foot pieces on hand in case I need it.

    Radiator mounting

    Good Morning members. I have an 84 Sierra, base model with a 350. I put in a new stock radiator last year, but the upper mounts for it are homemade. I have these brackets which look correct for my truck, but online images show different types of mounting. Can someone let me know if the pads...

    If you live in PA and see this truck it’s mine!

    Looks like an old D200 I had when I was in the Air Force. It was an excellent US Forest Service truck. Customized it a bit with Captains chairs out of a Dodge conversion van, 85 hood and cowl, and the 40 gallon plastic fuel tank out of a van. Even had the fuel door from a 79 F150 grafted into...

    Flywheel tooth count

    I recently found out the engine is hydrolocked. Having another engine put in with a new complete exhaust system. That explains why the starter would spin and eat the flywheel teeth but not turn the engine over. Last winter the oil on the bottom of the fill cap was milky, but thought it was just...
