    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...

    Who is or has run a 307?

    I'm interested in the running gear. How much?

    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...
