    new AC, dead at idle.

    OK, I finally took some time and read the book. Looks like the original idle solenoid was built into the Rochesters. there is actually a light green wire in the wiring harness that I’ve been wondering about for sometime that was never connected to anything, and that is the connection for the...

    new AC, dead at idle.

    OK, thanks. I found the Edelbrock one that goes with my carburetor and it’s pretty high dollar for $245. Just wondering what other options might be cheaper maybe this? ACDELCO 2142138

    new AC, dead at idle.

    just installed a completely new AC system in my 79. At idle, in gear, with air conditioning on, RPMs are dropping into the 400s and it dies on me when I try to move. I can adjust the idle up and that’s all well and good while the AC is running but as soon as you turn the AC off idle is running...

    diagnosing mystery rattle/ flex plate clearance

    yes that’s what i did. vacuum holds after line is clamped and it’s in drive. but now maybe it’s less of a lope and more of a stumble due to the big rpm drop

    diagnosing mystery rattle/ flex plate clearance

    well, it held a vacuum when I did as you suggested. Holds pretty steady around 18 or 19 Hg. here’s the clip: But whenever it goes to drive, it’s still a bit lopey. not as bad as it was when I first got it I don’t think but it’s definitely dropping about 200 RPM as soon as it goes into gear...

    diagnosing mystery rattle/ flex plate clearance

    yeah, it’s still leaking. It’s better than it was when i got it by far but I’m gonna have to address it again. I’m getting very different suggestions from Summit, rock auto and O’Reilly on the flexplate size. based on the block information and the transmission, summit is saying a 153 tooth and...

    diagnosing mystery rattle/ flex plate clearance

    I’ve had the flex plate off to replace the rear seal and there weren’t any cracks. But i’m replacing the flex plate anyway The thing i would really like to know is if that less than a 1/16” gap with the bell housing is typical?

    diagnosing mystery rattle/ flex plate clearance

    sorry i thought that was included 79 C10 2wd 350/350 Numbers indicate transmission is likely a rebuilt 79 350. The engine, at least the short block, is an 88 to 91. 305 TBI heads. Like I said, a bit of mish mash when I got it.

    diagnosing mystery rattle/ flex plate clearance

    i’ve had this 79 for a couple of months and I’m working my way through all its problems. It’s had a pretty good intermittent rattle when under decent acceleration that I have assumed might be broken blades in the torque converter. at least that is where the sound seems to be coming from. I...

    AC Head Control Options

    going to replace my AC heater control unit, it’s a little beat up. Would like to hear from some of you with experience if grabbing an OEM head or an aftermarket works better?

    Striped Vinyl

    hey everyone, I am just wondering if anybody has ever seen the vinyl on these seats? The RPO code is 62Y. I believe it is light, saddle, and camel stripe. it’s just that I’ve never seen them anywhere else and was curious.

    Which Mirrors are BEST quality?

    OK so stainless is a definite. Am actually going to LMC this week because my work takes me to within about 10 miles of there several times a week. Did you put those LMC mirrors on yet? I guess the main complaint I’ve been seen online is that there’re made so that they can go on either side...
