Engine/Drivetrain / Re: No vac dizzy

« Last post by Chevygold on April 14, 2024, 10:11:12 AM »

Here's a couple of pictures of what I've got, no weights, 7 pin ignition control module and no provision for a vacuum unit so looks like I'm in the market for a new distributor, wish I'd pulled it sooner now! Any suggestions and any to avoid?
Thanks
Graham

Electronic Spark Control. ESC Distributors are to be used with an ECM, Knock Sensor, Vacuum controls and are for retarding the ignition timing if spark knock is detected. What you have is an anti-performance distributor.

You want a standard HEI vacuum advance V8 distributor.

#1 follow up: the sender I replaced was stamped 80 on the base nut. So presumably its failure mode may've been the spring was shot resulting in open circuit and pegged needle.

Bought a JBL Flip, works well and sounds great.

Cigarette adapter USB to USB, came with cable, holds a charge for a long time.

Pardon my ignorance but what is a ESC distributor? I have a new cap which is the same as the one fitted, bought it as the contacts in the cap are very badly corroded/burned, I cleaned them as best I could but they're still not great. When I put my test machine on and did the cylinder cut test results were pretty much even except cylinder 4 which didn't drop much suggesting it wasn't doing much.

Thanks, Rich. I really appreciate your detailed knowledge of the gauges and senders. I'm actually good with mine as is since the dash and mechanical gauges(2) all agreed within a few percent using compressed air tool pressure to check calibration. It's really working!

PS- This is the sender I installed.

Keep up? Depends where you live and if everyone drives slow  Where I live you get tailgated at 95MPH on the highway so school bus trans isn't exactly the best option for that. The 465 is old school and good around town. Not made for today's crazy highway driving.

Should I even consider just finding a sm465 and np205 and putting it back to what it was? With 4th gear being 1:1 and 3.43 gears could it keep up in the expressway?
