    96k3500 454 Whipple Supercharger build thread

    I'm going to update this thread. Ok, the smaller gapped spark plugs or slight gash in coupler did NOT end up being the root cause of my problems; that is the misfire/studdering at partial throttle (low RPM, high load). I ended up testing the fuel injectors, the fuel system, a bunch of sensors...

    Thanks guys. I love the wheels and I love that the truck is running great again. I found a cut intake coupler between the throttle body and intake that was screwing everything up. Next step is meth injection.

    New tires and rims have questions

    4.5 backspacing on an 8 will probably push the front tires slightly past the fenders.

    Here's a couple more pics from today. I got my dual shocks and black billet grille back on. New engine pic. Damn these Vortec 454s are just ugly... lol.

    Swapping TBI 350 into 1999 suburban with blown engine

    Focus on just trying to swap the block. My guess is, if you have to ask how easy/hard it is, it might be too hard. :D I don't see the point in swapping a less efficient fueling/engine management system in for a better system. Seems backwards. A lot of people tend to want to go with our...

    Here's a pic with the new wheels. Also, my tuning woes aren't quite over yet; I am still missing occasionally. The root cause has something to do with my tune; I am working with Lyndon at Wester's Garage on a solution.

    Wheel spacers

    These are my spacers being custom machined for me on their HAAS CNC mill. This is the timken metal used to build my spacers. Jes sayin, if you are gonna do it, do it right. I think a set of 4 runs about $350. 2 will be <$200.

    Wheel spacers

    I had my 2" rear spacers had made out of timken steel from wheeladapter.com. The guy machined them while I waited at his shop. This is Fred Goeskes shop of drag race fame. Might be a little pricey, but if you are gonna do it, do it right. I wouldn't trust my life to cast chinese spacers with...

    Vortec 7400 rough idle

    Mine idles like crap and pretty much always has. Here's the thing, our trucks only have so much ECM adjustment away from stock when we begin modding with better flow updates. The MAF (volts vs. airflow) table really needs to be adjusted to compensate for flow mods, specifically the CAI in your...

    The Member Truck Thread

    Couple reasons. The last set, the lawless 8s, didn't really grow on me. It easy enough to sell perfect used rims for good $$$, that rim swaps aren't expensive at all. These happened to be the PERFECT offset (-1mm, 5" backspacing) and pulled the tires in 36mm! from the last set. My tires...

    Thanks! Here's a nice beach pic from today and a reminder to those that live in the Midwest why we suffer these fools in California.

    I think the idea is to keep as large of a gap as you can support for the most thorough combustion; I will go down to .026 if .028 ends up misfiring. I guess its some trial and error.

    Ok guys, I really wanted to update this for anyone else that ever bolts this supercharger up. It took quite a while and a lot of sleuthing and a little luck to root cause this issue. It drove me crazy because other people reporting similar issues NEVER reported back what they did to fix it. I...
