    Put that vette motor in the GSX. That will fix it.

    Fixed!

    Definitely a worn set of points. Put a brand new set of blue streaks in it.

    The broken breaker plate-

    New points and a new plate still didn't fix it. As much as I hate throwing parts at a problem, I put a known good coil in it- no change.

    I wound up swapping out the plugs. I had put a new set of AC Delco R44TS in it two years ago. Took them out. They didn't look bad.

    I found a set of brand new AC Fire Ring plugs in it. Box is date 1977. Gapped them at .030. Night and day difference. Runs good as new! Smooth as silk

    Workbench is a mess and the X is a filthy mess. This weekend she gets a detail and a long ride

    Every Camaro in the 80s and 90s had a "vette motor" in it. What did all the corvettes have? 2 bolt main, 2 bbl 305s out of Camaros?

    And, all '69 Camaros were Z-28s with an L-88` 427

    Fifth plug from the left looks slightly leaner...

    All except for one of my favorite projects, a customer's driver in the late '80's, a '63 Corvette sporting a '69 Z/28's DZ 302 engine. This time the Camaro engine was a big plus over 'vette, especially weekend evenings in Flushing & Flint, MI.

    4 speed and 4:11:1 to boot. That one is how I learned to row.

    Still not running right...

    90% better just cruising around. But getting into the secondaries on a hard acceleration, the car fell on its face. Not taking the power at all. Nosed over like I hit the Rev limiter. Swapped out the lectric limited wires I bought last year with the old ones I took off and problem solved.

    Not very happy with lectric limited. Thryre a year old with 3k miles on them.

    You're not the first one to have this problem. I've read about people having issues with those wires and I've had them on my car for a while.

    Just for the hell of it, I might put the Fire Core wires (Rob Ross turned me on to a couple years ago) back on next week to see if I notice a difference.

    Was there one wire or more that had higher resistance than the others?

    I was surprised when you said the plugs got it all. The age old Buick issue of ignition wires rears it's ugly head once more, not so lol

    I'll take it just the same.
    I didn't investigate them yet. I just threw the old set on last night and took it for a test beating

    Yeah, most all of those re-pro date coded wires are junk!!!
    You know where you can hold your hand IF you even bother to call lectric limited.
    Ask bigpig455 (Rhett True) his experience with these wires.
    Cost him lots of money for defective parts & was told basically to pound sand.
    AND, he's not the only one.

    Daves69 Too many cars too work on

    Ken Lisk had problems with his wires when building his GSX.

    Interesting.

    Tom's mentioned this previously in one of my threads, if I remember correctly. Looks like they'll work for "shows" but I guess with any other driving - that may or may not involve the secondaries opening - FireCores it is.

    It's too bad they can't get it right for almost $90.

    That's who I meant to say, Ken Lisk NOT Rhett True.
    Been a LONG time.

    Another thing I noticed is I had to adjust the idle down after taking off the repro wires. Also, it idles much better when you kick it down off cold idle warming up. Waste of $90 in my opinion

    I swapped out mine (yesterday) with the FireCore wires I bought a couple years ago.

    The car hadn't been started since last Wednesday. I set the choke and it fired RIGHT up. Like, it was legit noticeably better at both high idle and base idle.

    Looks like the date coded wires will go back on the parts shelf. Why can't these repro places make things that actually work?

    Why can't they simply make spiral core wires that appear correct with date codes and all. Who would know the difference?
