    NEEDED: Olds 307 engine wiring diagram

    I've been helping a friend replace the dead 307 in his 1988 Oldsmobile Custom Cruiser with a Chevy 454. The new engine is in and entirely ready to go. We want to sort through the engine bay wiring so as to attach the few wires we need (for the gauges, etc) and remove ones that serve no purpose...

    How many ground strap connections do I need, anyway?

    LOL. So the consensus says I need numerous more ground straps. I'll start working on that. Thanks, everyone. Hmm, I don't recall seeing that cable on my car... but I'll double check.

    How many ground strap connections do I need, anyway?

    My BBC-swapped 1980 Grand Prix has only two ground connections (not counting the interior). One is the negative battery cable connected to the passenger cylinder head (with no smaller wire going to the body), and the second is a small flat braided ground strap connecting the firewall to the...

    MONTE CARLO Hood vents, fender vents, or both?

    Do you also have the front vents from that same hood?

    4 wheeling anyone?

    I hate mud. Thankfully, here in Utah it is all about the rocks. My '98 TJ runs 35s, dual air lockers, a triangulated rear, and I just upgraded to a one-ton steering system and WJ brakes right before EJS got cancelled. :( I'm a member of the Red Rock 4-Wheelers and work as a trail official...

    80 Cutlass motor swap help!!

    Before you make any decisions, you need to have firm answers to the following questions: 1) What emissions laws must you follow, exactly? 2) What is your actual budget, all in? 3) <this one to a lesser extent> How fast do you want to go? Once you can spell out these answers, we can make better...

    Detroit Truetrac

    Yes, I do. However: THIS. Here's how I look at it: any money you spend upgrading your 7.5 is money you will need to spend again when you eventually stuff a stronger axle under there. Don't bother re-gearing or adding a limited slip to an axle you're just going to throw away anyway--that's...

    Detroit Truetrac

    In August 2017, I installed a TrueTrac into my 8.8 axle. Since that time, it has turned both rear tires every time I hit the throttle, even with one tire on gravel and the other on dry pavement. At the same time, when not under hard acceleration the differential is completely smooth and quiet...

    trans cooler

    Correct. They are more thermally efficient than tube and fin, meaning they cool better than a tube and fin of the same dimensions. That, too. Benefit #3: their sturdier fins don't fold if you look at them funny, so a stacked plate design allows for better airflow through its core and thus...

    trans cooler

    Because it is the larger of the two (11.31 x 13.36 x 1.91 in vs 11 in. x 9.5 in. x 0.75 in), I would choose the Hayden 698. In fact, I believe the Hayden 698 is the cooler I am running--when I bought mine, I picked the largest one Hayden built. This is exactly how I have mine set up. That...

    Coming Soon To A Gas Station Near You: Cheaper Gas!

    True enough. But if a company decides to promote their 'green' side and puts a few charging stations in their parking lot to encourage EV owners to frequent their business, well, who am I to complain? Sure, they absorb it into their cost of doing business... but it is such a dramatically...

    Coming Soon To A Gas Station Near You: Cheaper Gas!

    LOL. Let's just say I call it "balancing my carbon footprint."

    Malibu Exhaust

    I realize I'm a little late to this thread, but for anyone else who may be reading through it in the future.... Like the OP, I wanted a 3" mandrel-bent stainless steel exhaust system which exited behind the tires. I found the Pypes system with x-pipe and mufflers for about $500 (I see prices...

    Coming Soon To A Gas Station Near You: Cheaper Gas!

    Gasoline prices are falling? Good--I'm happy for you guys. Meanwhile, I just keep on daily driving for free (thanks to public charging stations) in my commuter EV.
