    8445 heads milling whats the max that can be removed and still be okay?

    Pay attention to the lifters. Take enough off and you'll want shorter pushrods to prevent the lifters from bottoming out. Depending on how much you've shaved off, the intake manifold may need to be shaved to get the holes to line back up.

    Dual fan

    Why would he search when he can trick you into doing it for him? :p

    Dual fan

    The stock harness cannot safely operate two fans. It should only be used as a trigger for a dedicated fan harness and relay setup that's connected directly to the battery.

    A tale of bad grounds and crankshaft sensors

    So, followup. Had an autocross this past Sunday. Car did really well until the last run, it popped and backfired approaching the finish. Scared me. it was the last run, and it was still running fine after I crossed the lights, so I loaded it on the trailer and decided to just get home and pull...

    Guest-Bots AI, They're Here And Choking Up Other Boards, Time For War!!!

    AI will ruin what's left of the internet that's not already ruined. Folks need to prepare for abandonment of mainstream social media and these forums will need to go invite-only at some point.

    A tale of bad grounds and crankshaft sensors

    It's a flat circuit board that plugs into the engine harness where the ignition/coil assembly plugs in. It loops the signals from the crank and cam sensors back directly to the ECUGN. If you get your COP harness from TurboTweak it'll come with the board:

    Anyone use the complete UMI rotojoint rear end control arm set?

    Looking for the answer you want and the answer you need is not the same thing. That Chevelle as shipped doesn't have nearly as much NVH mitigation as a G-body. The noise might not matter. But poly bushings will fall apart on you at some point. The poly eventually crumbles. Those delrin raced...

    Anyone use the complete UMI rotojoint rear end control arm set?

    They'll be fine for drag racing. The more important part would be UMI's lower control arm/coil over brackets with the multiple LCA mount holes. Very easy instant center adjustment, and that's what you need.

    A tale of bad grounds and crankshaft sensors

    Posting for posterity. I hope this helps somebody in the future. I just got done troubleshooting and fixing a really frustrating electrical issue. The car has an ECUGN and I'm using the coil near plug option. The car has been running great this year until July 13, 2025, at an Indianapolis...

    Anyone use the complete UMI rotojoint rear end control arm set?

    I don't have that exact set, but they are a superior solution to poly in every circumstance as long as you keep up with them. If you street drive it at all, you'll want to keep them clean and periodically disassemble them and get all the trash out. Might want to get spare delrin inserts for them...

    Rear gear ratio

    The 3.42s are optimal. If your ring and pinion are OK, there's really no compelling reason to swap them. If your gears are not OK (I chipped a tooth off my ring gear a few years ago), then plugging a set of 3.73s in will get some low end grunt without sacrificing highway driving. Go much lower...

    AC Accumulator

    They have it: Maybe not showing it to you because Canada? Use a VPN to get to the US version of the site and see if they'll let you buy it there and ship it to your house?

    AC Accumulator

    Rockauto? That accumulator was used on every GM passenger car from 1977 until 1984. It's not an uncommon part (Unless you're not in the USA). GM NOS probably not going to be easy to find. Most of that stock would have been run through in the 1990s with people doing R134 conversions. But they...

    rear disc brake upgrade

    It's a slippery slope. Any disc conversion for the rear that doesn't include getting rid of the C-clips will result in a system that's inconsistent. Knockback is real. It can cause a crash. So, if you're not ready to go all the way to C-clip eliminators or a full floater, keep the drums.
