    Road course/auto cross tires on 15" rim

    I used to build/race Dirt Latemodels, so please forgive me if anyone thinks this is just plain wrong... I just bought a set of these for one of my cars (15x12 w/ 5"bs), 275/60-15 M/T drag radials... I also bought a set of wide 5 adapters to adapt them to a 5 on 4.5" pattern. Anybody here try...

    Check the balance of your flywheels

    Here's a simple balance checking fixture I made a few years ago, wanted something to verify flywheel and PP balance at home. My first pass at this was just proof of concept using materials I had on the rack, basically angle iron and some cold rolled shafting. The arbor in the pic below is single...

    Any Dirt Track Mopars?

    Thanks for the comments guys. Here's where weedburner comes from... I've been told it looks real cool with the front end up in the air at nite, almost like one of those cartoon t-shirts with flames shooting out. Sometimes i'll put a little extra retard in the box just to get good flames :)...

    Any Dirt Track Mopars?

    Back in the early '80's I decided to build a dirt latemodel car for our local dirt track. The class had an engine setback rule, basically the #1 spark plug could be a maximum of 10.5" behind the upper balljoint centerline. The iron 440 out of my '70 Challenger was going to make the car pretty...

    Mike Finnegan, BlaspHemi, G-Force, and a grenaded tailshaft. Solution? Bangshift Billy (like HitMaster)

    I've got a customer that uses the 'tamer to control the hit of an adjustable Black Magic slipper clutch, used it to win A/S at NHRA's US Nationals on radials. Grant

    Mike Finnegan, BlaspHemi, G-Force, and a grenaded tailshaft. Solution? Bangshift Billy (like HitMaster)

    The Bangshift Billy and the Hitmaster do not function the same, although the end result can be similar. The main difference is the Bangshift Billy pulses a solenoid to control where the throw-out bearing lands during launch (timed fluid flow), while the Hitmaster uses the travel distance of a...

    Edelbrock carburetors and aftermarket air filters

    My Carter/Weber/Edelbrock carb's air cleaner was already close to the hood, but I wanted to upgrade from a 1/2" thick single stage nitrous plate to a much thicker 2-stage crossbar plate... I can't remember who originally made this drop base, might have come from an '80s Moroso air cleaner. I...

    Aluminum 833 build

    With a proper clutch, it will live @ 600hp even with slicks. Grant

    Aluminum 833 build

    I would not hesitate to use the aluminum case, as long as you also use a proper 600hp clutch. 2900lbs on a 10.4" organic disc diaphragm would be ballpark, as would 2300lbs on an organic/metallic dual friction disc. Grant

    Rear suspension suggestions needed

    Hi padam, thanks for the feedback! There should be a groove milled in the 'tamer's threaded rod, also detent balls installed in it's inner dial as well as outer slide bushing. I added those back in 2016, they are supposed to keep the adjustments from casually rotating due to vibration. Can you...

    Gearing and Rear Discussion TKX

    Engine power/torque isn't much of a factor when it comes to breaking rearends. Even a 7-1/4 can hold up to a 646tq engine in 1st gear. The real factor is how much peak impact is sent to the rear while the clutch is engaging. These cars rolled off the assy line with a B&B pressure plate. The B&B...

    Rear suspension suggestions needed

    Let's say the 489 makes 530ftlbs. Let's also say it makes 530ftlbs from 3000-5000rpm. 530ftlbs@5000rpm=505hp 530ftlbs@3000rpm=302hp If you want an engine to make HP during launch, it needs to spin some rpm. With radials the tires also need to dead hook. With hooked radials, a car needs some...

    Clutch

    If you fall into the trap of buying more clutch than you need for a street/strip application, it will make your car harder to launch when you take it to the track. More clutch than you need also inflicts un-necessary wear/tear on your drivetrain. A twin disc will typically have a soft pedal and...

    Car Leaving Better, Couple of Videos

    Hard to read the tach but overall, the clutch was doing what you want it to do. You want it to slip to keep the engine up during launch, but on the other end still pull the engine down enough to hold in high gear. It was holding high gear just fine, I would bump 2-step 500 per pass and see where...
