    Opinions on Radiator Usability

    My assumption is that is an original Harrison radiator. The original petcocks are pointed down (there is a matching hole in the radiator support) and were no mess to drain. I've only seen that on the originals. I don't have any original dimensions for the radiator (I replaced mine in '91 with a...

    OEM air cleaner size/dimensions for 1983 GMC pickup?

    FWIW... The Rochester 2G was was only available on a corporate blue ('78 - '82) 305 small block in 1978. The dual jet was standard in '79 and only 4bbls from '80 - '82. Of course, anything is possible to swap around.

    Speedometer Cable Discovery!

    I take the 'Made in Mexico' as a good sign too. Probably still from OEM production.

    Speedometer Cable Discovery!

    That's good to know. Parts are such a problem now, especially when everything you own is obsolete, from defunct companies that spun off and bankrupted their suppliers first before their own pseudo/phony bankruptcies. Good lunch! My lunch yesterday!

    Need some HEI Distributor knowledge!

    An HEI could make an old Ford 6 nearly maintenance free for hundreds of thousands of miles :)

    Convert crew cab to have rear A/C?

    Just make sure you use anything but an R4 compressor.

    A Couple of JY Oddities (at least to me)

    Saw this '76 Sierra Grande (half ton) a little while back. While the aftermarket A/C looked like any other under the hood, (York compressor, cumbersome bracket and adjustment, undersized condenser), it was the 'control head' that caught my eye; Rotary knob is a thermostat and the standard...

    '87 R20 AC Recharge

    I believe there were more changes again for 609 Certification for 2018, as HFO1234yf and CO2 (talk about inefficient) become reality. The march always continues on in the name of the environment via increased regulation, expenses and taxes, particularly with refrigeration.

    '87 R20 AC Recharge

    "You will have to dump the remaining R12 before anything else is done. You can legally release it to atmosphere, but certified shops cannot" I'd like to point out that venting any refrigerant is a $10K fine per occurrence for anyone. There have been idiots that were stealing outside...

    Economy TBI for 292

    I appreciate that, but I think I'm good for now. I have collected a few, and do have a '95 TBI V6 MEMCAL which gives me at least one appropriate CALPAK for limp home. My dilemma right now is whether I want to go TunerPro RT or Tunercat. I have a MPFI idea on the horizon for the Caprice (still...

    G30 van question

    I'm at a complete loss on both these. I didn't think that style choke made it out of the 70s in the Chevrolet division.

    Economy TBI for 292

    Finally getting around to building my economy TBI for my 292 L6. Got the manifold and a throttle body. In case that unit looks small, it is. This is the 2.8/3.1 V6 unit. With the original 1bbl being only rated at 250 CFM, I think the smaller unit is more appropriate for a stock 292. I...

    Factory speaker location????

    Nope, (outgoing) air vent. Novel idea, how does it work?

    Bed swap compatibility

    Last year without filler doors is '78, but I would be concerned about all the running changes, especially with a '73. With that said, I don't know.

    New guy in OH, bought my second truck in 3 months! (Help?)

    Wow! The '85 is really nice, though I am partial to your '79. I thought the '85s were all ready rusted when I left Ohio in '84!

    1994 tbi 350 swap

    That does look like nice stuff at good prices. I've been building mine myself. I'll have to take some pics if I finish it today. My donor harness was a '93 dual A/C Surburban. Talk about extra wiring to remove! This is what I started with; Unless you love this sort of thing (like me), Larry's...

    Trans fluid change

    Absolutely! Seems like some are already on the filter pipe, as you have seen, and others will be in the package, ready to install. Some people can do a lot of damage to the bore trying to get the old seal out. Forgetting an o-ring (T400) or the seal (700R4) on the filter can be a memorable...

    Buzzer for headlights

    That's a buzzer, not the optional chime. Everything should be there to plug in a chime, if you can find one. If you pull the buzzer, there should be extra terminals under it that are unused. I'm transferring my knowledge from various GM car lines of the era, so there is a remote chance that the...

    Buzzer for headlights

    Does the fasten seat belt light still work? Part of the same unit and some were unusually 'fragile', IMHO.

    Trans fluid change

    The OP will have a Turbo 400 if a 3 speed (probably not), and a 700R4 with 4 speed automatic. Just watch the o-ring or seal on the filter pipe in either of these transmissions. I'm a big fan over changing over the Dexron VI as GM says is fully reverse compatible.

    1985 Silverado K30 w/454 correct a/c compressor??

    Excessive high pressure is a lack of cooling on the high pressure side of the system, i.e. poor air flow over the condenser, internal condenser issue, blockage, or an over charge, not a compressor problem.

    What is this?

    Cool, a picture of one on the side of the 292. My '78 w/T400 didn't have one.

    New dash pad from Cheyenne Pickup

    I wondered how the speaker grills were covered. That looks good!

    What is this?

    That's good! I was concerned you were in for some surprises.

    What is this?

    Yes, hydroboost, 1 ton system. I was guessing an engine swap too, as the fan blade is so far out of the shroud, as a BBC fan shroud is too short for a little SBC.
