    1983 454 vs 5.3 LS for towing

    https://derale.com/product-footer/transmission-pans/cooling-pans/14204-detail I use this in conjunction with a fin type cooler in front of the radiator. This pan is great. It holds more fluid and comes with a port for a temp sending unit. In the peak of summer with a 2400 stall converter...

    1983 454 vs 5.3 LS for towing

    The 454 is a much better option for towing than the 5.3. It makes a ton more torque and torque where you need it. I'd use the 700r4 too because it has a very low (high numeric) 1st gear ratio that makes it much easier to accelerate from a stop when towing a heavy trailer. You mentioned...

    @Rusty Nail The front side marker lights came yellow from the factory. Clear was never a factory option. Locally it would not pass inspection with clear lenses. You might pass inspection if the bulbs were swaped out for amber bulbs though. Meh, it's a stock appearing longbed with the exception...

    It's looking more like NO2 is the best option. I'm not willing to give up the air conditioner or remove body panels. The truck already has a 2500 stall converter and i don't want to go any higher because it could reduce drivability on the street. And as far as wheels go I don't think the expense...

    I might try aluminum wheels. I saw a YouTube video where they did a back-to-back chassis dyno test with big heavy mud tires vs light weight wheels with drag radials and the measured difference was huge. I don't remember the exact weight difference but it was like a 50 lb savings and 75...

    60' times are 1.7 I run about 20 psi and there is no noticeable tire spin during the launch

    The tune is close. We tuned it on the engine dyno for the best timing and jets. I expect that probably changes with the engine in the truck because of the heat so maybe there is something in the tune. I will need to get an o2 sensor though. That should optimize the current configuration. I'll...

    RPMs are relatively low in 3rd gear at the end of the track. Relatively zero tire spin with the 295 drag radials. Based on these responses I could try a higher numeric gear ratio or nitrous. No restrictions on nitrous in the 7.5 truck class. The restrictions are 295 tire or smaller and no trans...

    I just realized more details on the current configuration of the truck will be needed: Big block Afr heads 236 degrees intake duration at .050 Th400 2500 Hughes stall 4.11 locker 295 MT drag radials

    Summarized in the title. I'd like to increase the et of this truck from 7.70 to 7.50. As the truck sits today it runs consistent 7.70 at 90 mph. The local 1/8th mile has a 7.50 index truck class with a sizable purse. I'd like to compete in the 7.50 truck class. This past Friday I went to...

    Amplifier Wiring 4ga Pass-Through to Cab

    Thanks @Grit dog This is the method I chose. It was easy to route the 2ga and the wire is mostly hidden. I was able to route the wire inside the passenger front fender down under the rocker panel and then up through the cab corner using the factory rinse plug in the cab corner. I made a mount...

    Amplifier Wiring 4ga Pass-Through to Cab

    I'm interested in how other board members are passing 4 gauge audio amplifier wiring through the cab. My amplifier requires a 4 gauge wire attached directly to the positive terminal of the battery and I don't want to drill another hole in the firewall if it isn't necessary. Pictures and...

    275/60r15 vs 255/70r15 on stock rally wheel

    Good choice on the tire size. I've gone to great lengths to get an original set of unbent 15 x 8 rally's on mine. I like the rally's. A lot. Mine's a stock height longbed and I'm planning to upgrade to 265 70s when my 235 75s wear down. I think the short beds look great with the 275 60s but it's...

    How much HP and Torque for Daily Driver

    Go get a vortec 350 from the salvage yard for $200. Put a quadrajet intake and long tube headers on it when you swap it into your truck. All accessories and water pump from your current set up will bolt right on. It will he 300-310 horsepower and 400 lbs ft at the flywheel. You'll have more...

    How much HP will a th350 handle? New motor!

    @1979 K10 Glad you kept the AC. Good choice on the new motor. That thing makes 450 lbs ft from 2800ish to 5600 rpm. It's gonna be a blast with those gears. I dig the air cleaner element too. Keep us posted and let us know if or when the trans gives up. Your trans was built at one point so maybe...

    Hooker 8525-4HKR ... Thoughts?

    I'd be interested to learn how they do. They sure look nice. Based on pictures alone, they look like they'd flow well. At that price though, I wonder how much better they are than a standard 96-99 vortec manifold which can be sourced pretty easily, though they wont have the D port shape. Now...

    New to me wheels and tires

    @45tt I agree. I found another four rallies and I need to confirm they aren't bent before I repaint them. The new plan is to run four 255 70 15 tires and only swap the Mickey Thompsons if I visit the track. I'd like to run a 265 70 15s if I can find a street tread pattern. @BRetty it's stock...

    Driveshaft vibration

    The replacement is straightforward, remove the driveshaft, then the tailshaft, and remove and replace the bushing. I tried replacing the bushing on my own and ruined the new one. Rather than buy another and ruin it too I went to the salvage yard and got a "good" tailshaft off an astro van and...

    New to me wheels and tires

    My truck had the steelies and dog dish caps from the factory. It took me forever to round up a full set of rallies, and it turns out two of them are bent, but you can get an idea how much better the rallies are than the steelies. The steel wheels are only 6 inch wide and the rallies are 8. It...

    Driveshaft vibration

    For what it's worth, the Burban with the worn tail shaft bushing did not leak fluid. It did exactly what you describe, shake the floor. A glass of water in the console would definitely have rippled at the right speed. You've been all over your truck diagnosing the problem, and unfortunately...

    Drip Rail

    81-87 drip rails and mounting bolts are satin black. That said, it's your truck! Make em any color you want! I think they look great painted body color on the white truck in this thread.
