    New Truck Mysteries!

    Thanks Jim. I am saving up for upgrades this winter, what would be a good CFM rate to look at, considering I eventually want to get this motor making 600hp/600ft-lb? Or will it run like crap at a high CFM if the motor is mostly stock otherwise? I was looking at a 750cfm Demon.. they seem to run...

    Exhaust opinions

    I like how the ones on my truck are currently, turned out behind the rear tires. Then if I'm working on it in the driveway, I have a little extra distance between me and the exhaust fumes. Not sure how much insulation and soundproofing your truck has, mine has about zero. Definitely plenty of...

    New Truck Mysteries!

    Hey guys, Thanks for the comments. I got her back from the shop today finally. She runs like a dream now on the manifold vacuum port, and got an overall inspection done. Accelerator pump was shot, and I will need to do some ball joints and tie rods up front. The front axle is actually a 3/4 ton...

    Trying to figure out the correct calipers. Any help?

    If they're Danas, you should be able to ID them, I need to do the same with my truck once she's back from the shop. Similar situation, I have 3/4 ton conversion from PO, Dana 60s. Pulls a little to the right if I brake hard at a decent clip. Grab a copy of a Dana service manual, if I recall the...

    New Truck Mysteries!

    I have a shop in northern MN looking at the timing, carb and alignment for the next few days. I want to set a good baseline so I can drive the Jimmy daily, and so far have been super helpful... still really curious if you guys have any thoughts on the other questions above though. Long term, I...

    New Truck Mysteries!

    Thanks guys! I'm picking up a light this weekend, along with a vac gauge and tachometer. I'll take a look inside the distributo, too. In another thread HotRodPC said some stuff about the accel pump on the carb, and its real dirty around it.. I suspect it's shot and is why punching the gas just...

    New Truck Mysteries!

    Hi guys, First off, I'm new to working on trucks entirely, so this is going to be an awesome adventure for me.. hopefully! You guys have already helped me fix my doors (the slamming sticky) and I've been reading a ton of good info here, so thanks! I picked up a 1982 Jimmy that's been modified...

    Edelbrock Carb #1406 Calibration & Reference Chart

    Does anyone know the "factory" settings for the screws? I read somewhere to turn them all the way in, then back them out 4 1/2 rotations, but that seems like it might be kinda rich compared to what I usually hear for carbs. Anyways, I was messing around with tuning it yesterday before I realized...
