I finally figured out that I had accidentally reversed the "S" and "I" small wires on my starter solenoid and that's why the truck wouldn't start. So now it's running, but I need to take it out for a test run to make sure all is well.

A simple bad ground can cause lack of lights and electrical gauges.

A regulator won't stop it from starting, only from charging. It will run without charge for a bit. Seems more like a connection issue perhaps. Make sure the grounds to the motor are clean and good, as well as the positive to the starter. Also, a...

There really isn't much for tuneup with the hydraulic lifters and such. These are high compression motors and heavily built so unfortunately vibration comes with. If you have a manual transmission, it can be the dual mass flywheel getting bad...

Technically it will be a different perch for the 352 (FE) to the 351W. Not to say that perhaps spacers could be done. Most commonly the advice is to get the right perches which can be much easier said than done.Did a little looking, it looks...

Depends what motor came out, On the brownie, that is in reference to an over/underdrive add on?

Seems like a logical way to go. If everything else looks right, about all that is left to kill ride quality.

Only way the shocks can cause harsh ride typically is if they are largely stuck. I have seen that - they wear to the point of siezing. You should be able to go to the rear bumper and give a good shove down and have it bounce back up. If it won't...

Generally 800 is the proper idle setting, then set the timing accordingly at idle.

Check with a driveline shop is pretty much all I can think of.

You can also look at car-parts.com. They have listings for many yards. Swapping cabs will also require getting the VIN updated for your truck. The VIN of course is visible under the windsheild. If it doesn't match your title/registration, it can...
