    Inconsistent tapping from 400 sbc

    Run it without the belts on. That will eliminate tons of white noise. Check all your pulleys while your at it.

    Latest Lost Cause Project: 1979 Z28

    Funny story.. a guy i worked with raved about his friends 81 TT/A that he had back in the day. He was literally insulted when i broke the news that it was probably the lamest trans am ever, even with the turbo. He was driving a Citation at the time. I told him it's all relative..

    Latest Lost Cause Project: 1979 Z28

    A quick Google search confirms your are mostly correct. Manual z28s got 3.73s and autos got 3.42s standard. I am shocked GM had that much of a pulse back then!

    Latest Lost Cause Project: 1979 Z28

    3.42s would be like winning the lotto. In addition to leaving the factory with no horsepower most of those cars got 2.56s, 2.73s and the occasional 3.08s. It was a very dark time...

    That would have been a good canidate to weld a nut to. Either way, kudos for getting it out..

    Two things Do not flap wheel it. You'll create a low spot in the deck which will cause all sorts of other problems. I wouldn't condemn the helicoil just yet. Pull it out and if the threads look good I'd install a new one. After that stud that hole and go racing.

    305 to 427

    Is the 427 a tall deck motor or a normal BBC? If its out of a kodiak or c60 its a tall deck. If that is the case normal 454 headers won't fit properly.

    Pinion depth way off

    to make it easy to explain lets say the race has an OD of 5". Half of that is 2.500". The natural assumption is the bearing cap and the housing are both 2.500" making the parting line dead nuts in the middle. Well the bearing cap could be 2.450" deep and the housing side 2.550". You would need...

    Pinion depth way off

    You have to verify that the bearing cap is actually dead nuts half the race diameter. Not terribly uncommon for it not to be. Also make sure your 1/4 plate is .250. A dial caliper is far from ideal for this measurement. A depth mic is what you need. I would also start with the factory shim and...

    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.

    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.

    Bad miss - could use some thoughts from y'all

    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.
