    L31 to MPFI with other than Marine Intake Manifold

    I know I am a few months late to reply but I have been working on an L31/350 Vortec MPFI intake manifold. I am still early in the testing stage. This is a dual plane intake manifold with an estimated RPM range of 1,000-6,000 RPMs (I could change the base manifold to be a 1,500-6,500 RPM...

    (NJ) 2005 HD Conversion

    I am just gauging interest in the front end off a 2005 2500HD. The only thing that is needed is a new lower bumper valance since this one is cracked up. I believe you will need the fenders, radiator core support, hood, grille, front bumper, horns and bumper brackets. If nobody on here...

    2002 4L60E

    When I check on RockAuto, I see the 2002 4L60E is a one off year. I know all of these NBS 4L60Es are physically the same size and bolt pattern. Does anybody know what is different about it? I am looking for a vehicle to install my 2002 4L60E into but I want to know what I'd need to change.

    2002 Tahoe part out

    2002 Tahoe Z71 with 220k miles but pretty much any wear part (drivetrain, suspension, fuel system) has been replaced in the past 45k miles. I originally found a small pinhole in the frame that I was comfortable repairing. When I dropped the fuel tank, the entire inner rail is pinholes...

    03 Escalade ext cranks then dies

    If you turn the key to the start position and let go of the key so it returns to the run position, does it continue to crank for a few seconds?

    Battery tray coating suggestions?

    MasterSeries primer and paint. I'm in the process of doing my entire frame, body mount cups, battery tray, rear axle, lift components, etc with this stuff and its turning out amazing. They claim it has something insane like a 14,000 hour salt water life. It was originally designed for bridges.

    Budget lift dont wanna spend over 600 how high can I go

    If you are handy at welding and fabricating, you can do a 3" body lift for $140 (3" blocks, class 10 bolts and steering shaft extension) like I'm in the process of doing. You will have to make make your own transmission cooler brackets, bumper brackets (front is very easy) and filler neck...

    2002 5.3 Crank appears to wobble at idle

    I think you'll be okay. Now you have me curious and I want to check both my LS trucks but I currently have both motors on engine stands at my mom's.

    2002 5.3 Crank appears to wobble at idle

    I honestly don't know. The harmonic balancer does exactly what its name suggests; it reduces engine vibration. I suppose in an extreme circumstance that it could prematurely damage main bearings but I doubt it. I'll be honest with you, I don't even know how to verify if the hub has spun on...

    2002 5.3 Crank appears to wobble at idle

    I'll look at the 5.3 on my engine stand later on. If they have a rubber insulator, it is possible that the rubber is broken and distorting the pulley. It was common practice when assembling the old small/big blocks to verify that the rubber insulator didnt break. This would allow the pulley to...

    [Theoretical] What if we were to move away from the 4lXXe and how would we do it?

    Doesn't the 6L80E have a TCM? I am sure their is a company that makes an aftermarket TCM but it would still be a lot of money, time and fabrication.

    2002 5.3 Crank appears to wobble at idle

    I have never paid attention, do these balancers have a rubber insulator?

    Wow, glad you're okay... How fast were you going when this happened?!

    2002 Tahoe Z71

    I've been trying to time priming and painting the remaining 3 body mount cups and frame sections in between rain; it hasn't happened yet so I removed the motor. I originally tried taking it out the top but chickened out lifting it that high on my hoist so I ended up removing the radiator...

    2002 Tahoe Z71

    They used body filler over bare (sanded) rusted metal. Their are ways to make that work for a few years but it's a no-no. I'm not much of a body guy. I've done a few cab corners, outer rockers, patches and lower quarters but the mechanic at my job worked on classic cars for 10+ years prior to...

    2002 Tahoe Z71

    I can't buy that portion of the inner wheel well that butts up against the dog leg, can I? I know I can make it myself if I absolutely have to.

    2002 Tahoe Z71

    I took the day off work to work on the truck for a few hours and hang out with the wife and son. I have looked at diagrams showing the side skirts but wanted to know exactly how they were attached; since I need to do rockers anyway, I figured I'd take one side off to give me more room to clean...

    2002 Tahoe Z71

    I watched a video on YouTube. The guy takes a long stretch of cable and inserts it into a piece of 1/2" conduit. He hooks a drill to one end and the other end has a washer and chains. When the cable spins, it scales the frame with the chains. Very clever. It will also help break up any rust...

    2002 Tahoe Z71

    Yup... I'll fix it while the truck is off the road. I have a few spots I need to cut out and patch first. Truck needs a new fender and that door. I'll finish the body lift this week and start tackling the motor over the weekend. I want to needle scale, wire wheel, prime and paint the front...

    2002 Tahoe Z71

    Awesome news. I am going to spend a lot of time internally prepping what I can with chains, air and a pressure washer beforehand. I don't ever want to touch the frame again.

    2002 Tahoe Z71

    I've used bridge primer and paint on the body mount brackets and metal cups. Half the body lift is bolted in, the other half has to come out for primer/paint. 35's are looking small now... 10.5" total lift (plus 2.5" in tires) next to me at 6'4

    Common rust issue everyone needs to check for!

    As far as body work goes, I use a Hobart 140 mig welder for sheet metal and an Eastwood 250 mig for anything more structural (like plating the frame). Buy a used 130-140 amp mig welder with gas shielding and go to town. I always try to cut below the body line seam to make blending paint easier...

    Common rust issue everyone needs to check for!

    I currently have my Tahoe torn apart for repairs and figured I'd take care of all of the rust. My truck lived in MA for 12 years and is now over 5 years in NJ. Key rust spots: Rear inner wheel well seams Rear section of rear passenger doors to inner wheel well arch Lower rear quarters Inner...

    How big is this lift?

    You can compare the body line down your door for yourself to determine the size of your lift. I'm on 315/70/17s which translates to a 34.5" tire. To me, you have a larger gap between your front tire and fender than I do on 7.5". Your rear tire to fender ratio looks very similar to my truck at...
