    Getting an 87 V25 C6P HD to sit close to level

    Hey, that pics helps. I'm leaning towards just keeping it simple and cheap and getting the 1" ORD add a leafs. 1" doesn't sound like much, but it will take out a lot of that rake. Based on other pics I've looked at, I think the c6p trucks sat about 1-2" higher in the rear than a non-c6p truck.

    Getting an 87 V25 C6P HD to sit close to level

    Anyone know how a C6P truck sat when new? Right now my truck sits a little over 2.5" lower front to rear. Trying to figure out if my stock front springs are sagging before I get 2" lift springs and end up sitting higher in front. Also considering splitting the difference and getting some ORD 1"...

    Too dumb to figure out last steps to troubleshoot EGR

    Got the braided ground strap from the firewall connected to the same bolt on the back of the engine that has a single ring terminal with 2 ground wires running to it from the wiring harness. New distributor didn't change anything. But no regrets on replacing it since old one was crusty and...

I've read that this ground is pretty critical to ensure the ECM does a good job of getting and interpreting clean readings. I can't easily see...

    Thanks for the welcome...still working on this thing. Current status: -New Map Sensor -New IAC Valve -New cap, rotor, plugs, wires -EGR capped at solenoid so it won't open up for the time being. Pretty sure solenoid (or ECM?) is bad and it was opening up at low RPMs when it shouldn't, causing a...

    Too dumb to figure out last steps to troubleshoot EGR

    I've got an 87 V2500 w/ a 5.7. It's a 8600 GVW truck w/ NA4 code. I'm to the point where I know that with the EGR hooked up, I've got ~21 in. at idle but revving up to 3000RPM and holding will drop to a steady vacuum of 15 in. I then unhooked my EGR solenoid and see that vacuum stays good @ 21...
