    main and rod bearing help?

    Discuss with your machinist what bearing is correct. People forget not all bearing manufacturers are the same, and they have different lines of bearings, for different driving conditions. So what bearing to use comes down to what you will be doing with the engine, rpm, heat, load, etc. I will...

    6.0 not quite running right

    Small block Chevy, 7000 rpm, yeah you need decent dollars. At the least a good set of heads and intake, decent cam with enough duration, balance the bottom end and arp rod bolts a must. You probably can’t push it past 6500 because it physically can’t move the air at that speed.

    Easiest way to drain a fuel tank on a non running car.

    Electric pump? Jump power and ground to it. If not and you don’t want to keep the tank an AIR drill drill a 1/4” hole in the bottom. Key word is air drill and drill slow

    leak somewhere

    Do you think you have a leak or just trying to check for leaks and fill with coolant? You may just not be getting a good seal from the tool to the radiator. The one I have at work will do that and while the air is flowing I have to keep pushing it down and kind of rocking it back and forth...

    GM Truck Recalls

    I’ll be honest I never bothered to read the article because i figured it was the same as every other recall notice I read at work. Also I was more or less making a general statement in regards to all recalls as opposed to just this one.

    GM Truck Recalls

    This is what the inflators wind up looking like. And I wouldn’t say gm was necessarily trying to fight it, federal law mandates manufacturers must make a recall within I think 30 days of knowing about a safety issue, but it takes months or years to design and safety test the parts, produce and...

    HELP Ignition igniting frustration

    Possible you have the wrong cap or rotor and the gap is too big? Do you have a hot spark if you check out with the coil wire?

    Modern Fluids Poll

    Brake fluid should be flushed out roughly every 5 years, it absorbs moisture, moisture boils at 212 not well over 400 like brake fluid. T case and diff services should be done roughly 50/60k miles as should power steering fluid, we have seen evidence through customer cars that those who have...

    1 7/8 inch headers

    the problem is the more aggressive of an engine you build, aggressive cam,rage runner head, single plane intake, etc the less an engine likes to lug around at low rpm. All those pieces are mean to horsepower aka high air flow seeing as hp is torque times rpm divided by 5252. You don’t tend to...

    BUILD THREAD Rustier then I thought!!!

    You can take a real good picture of that lock and send it out to a company I can’t remember they’ll send you a key it’s like $45 used to do it at work for people all the time, now we keep master kits of the keys. Besides that weld, drill, lug nut extractors, depends how much time you want to...

    CHEVY SBC 400 ID

    I don’t know what kind of motor you’re trying to build as far as power level is concerned and I do realize this is probably a lot more $ than those 2 used blocks but personal experience here only way I would build a 400 based engine for anything is with an aftermarket block, little m is...

    Adjusting rear control arms?

    Not trying to argue just understand, how would you use the center link to center a steering wheel? I know we modify them all the time to adjust bump steer, frame clearance etc I’m just not sure how you could straighten a wheel that way

    Adjusting rear control arms?

    Do you have a reason why they need to be same length? Adjusting the different arms to different lengths is all part of his you take an ok car and dial it in. The adjustments are to take into account any inconsistencies, do you really think every single metric frame has all 4 control arm brackets...

    My nearly new, 0 owner 2017 Dodge Challenger GT

    If you have the evic that shows the trans temp on vehicle info, you don’t need a scan tool, just need trans temp I want to say 85-125*, engine running 30 seconds in park neutral reverse drive then pull the plug and fluid should trickle out, however those trans are sealed and filled for life so...

    Another vibration thread!

    What streetbu said did it start after the pinion seal replacement? If you didn’t tighten the pinion nut right that’ll give you all kinds of issues. Correct way to do it is remove the rear gear carrier measure pinion preload before disassembly then tighten but until you get desired pre load. Flat...

    Taking Bets!

    Unfortunately a lot of people view they dyno as a way to earn bragging rights by having a piece of paper, and they have no interest in using it as it was designed. I like to call it the dream crusher because everyone thinks their 9:1 350 with fuelie heads makes 500 hp

    Taking Bets!

    Dynos have become such a joke. Everyone wants their stuff dynoed just so they can have some really high number to brag about to other people. Their true purpose is as a means to test and verify the build of an engine prior to install in car or prior to a race, to verify the effectiveness of a...

    Taking Bets!

    It depends on a few variables including tire size and gear ratio (max mph speed on dyno rollers) but you normally try to get it into direct drive if not then assuming th350 second, don’t want to be in too low of a gear or you pull too quick to really load the engine and measure full torque the...
