    Diagnosing mysterious sound from Tran/Tcase

    You can unbolt the converter from the flexplate and start it up. That'll point you in the right direction.

    Selling my 1961 CJ5

    Neat rig. I have a Scout that I'd like to do the rear conversion to. I love the bikini top. Thats the best way to travel

    Bad miss - could use some thoughts from y'all

    That works too.

    Get an infrared thermometer and check temps at the exhaust ports. Your cold cylinders are the dead ones. Start diagnosing from there.

    Replacing a single frame rail, can it be done?

    I've seen this done dozens of times in the HD world. Lots are replaced due to collisions and other failures.

    JamesSam's TBI Code 21 Test Thread

    Idle voltage should be a bit lower. I think the spec is .40-.50. If you are unable to achieve that you probably adjusted the idle screw too high. The IAC should be able to compensate for the adjustment. Also it's good practice to use the computer ground for your DVOM when reading voltage off...

    Check the range, not just idle and WOT.

    I think a rod spun a bearing in my rebuilt 454

    Was the block align honed? This is a very important question..

    I think a rod spun a bearing in my rebuilt 454

    That won't work. That rod and it's partner will need resized and the crank will need turned. To the OP- Unfortunate turn of events. You'll have to tear it down and determine what caused the failure. 4k miles is nothing. I'd guess it was not properly cleaned before assembly.

    Stock Cold air intake performance upgrades

    I gotcha now. The intake pad was also heated with the exhaust crossover which helped with cold running. It's mind boggling how GM came up with all this and made it work.

    Stock Cold air intake performance upgrades

    See my other post. The system is in constant operation and tries to maintain a consistent air cleaner temp, even after the engine has reached operating temp

    Stock Cold air intake performance upgrades

    What are you pointing at? I'm not surprised the thermal system is disabled. 95% of people have no idea why it's there or how it works. It won't have any effect on cold starts.

    Stock Cold air intake performance upgrades

    I know cold dense air increases power. I'm saying he won't do better than the factory setup. Cold air isn't that simple with a factory carb either. The thermal vacuum switch is designed to keep the air cleaner temp at 115 degrees. Keeping the air temp consistent keeps the mixture proper...

    Stock Cold air intake performance upgrades

    Cold air intakes are a joke to begin with. Way too many variables to quantify a 10-15 horse "gain" on a chassis dyno. Folks hear more intake noise and think they gained 40 horse.
