    First real test drive today, after V8 swap.

    For those that don't already know: 89 RCSB K1500, 5-speed, 5.7L V8 swap, aluminum heads, and Hedman headers. I got the front end and suspension all back together yesterday. I actually renewed the registration and added this Heap to my insurance :eek:. Cranked it this morning and it fired...

    Dug into my front suspension today. Now I have a steering knuckle question.

    I'm replacing the upper control arms, lower ball joints, lower control arm bushings, sway bar link bushings, and now I have to replace the wheel hubs. First, there's this little issue, but I can fix this. What a mess, although, I had been planning to do this for a long time now. Just...

    Oil pressure gauge always pegged.

    Title pretty much says it all. Sorry if this has been asked or posted before, but I DID search to no avail. Everyone knows by now.... 89 RCSB 5 speed, V8 swap. I'm almost ready to try breaking in the new cam (lol we'll see how that goes). I'm not sure that the oil pressure gauge on this...

    Cranks but won't start.

    All, the V8 swap is now complete so I'm starting a new thread, because now we are on to troubleshooting. Just in case, 89 with a 94 5.7L 5-speed. I found the aforementioned miss. Somehow, the #8 spark wire was disconnected. Upon connecting that, it started right up, gave me a few hiccups...

    Another mystery wire.

    So, to get a wider immediate audience on this, I'm making a new thread instead of updating my V8 swap. Who can identify this mystery wire and what it's supposed to plug into? First person who says O2 sensor, I hate to burst your bubble, will be incorrect. Or maybe I have the O2 sensor plugged...

    Which computer do I need?

    I can't find a CLEAR answer on which computer I need, or what I need to do to the two that I do have.. We all know my info by now, but, I'll put here just in case. 89 RCSB 5-speed, 4.3L to 5.7L (from a 94 K2500 auto) swap. My OEM computer does not have a service number on it. There are...

    Air cleaner assembly. Paint it or not?

    I found this in the yard, of course. I was going to leave it as it to get that patina old school look. Then, the Wife sees it and said Ewww you have to sandblast and paint that! It looks like $h1t on top of that shiny new engine. Sigh.....

    TBI upper gaskets

    So, I rebuilt the TBI on my V8 swap. It was pretty straight forward. Got it all together, bolted to the intake manifold, and then went to put the "lid" on the TBI. Mine is plastic (as opposed to the metal lid that was equipped on the 89 V6 model). After scrubbing said "lid", I noticed a...

    Factory Engine color?

    I've searched the forum, google, and went through my pics. I can't believe I don't know this... What color would my engine have been from the factory? In this case, I'm keeping it whatever color it would have been on an 89 RCSB K1500. I was going to assume Chevy orange, but I wanted to...

    Correctly setting valve lash.

    I'm trying to set the valves on my mostly stock build. The service manual is too vague. "Tighten the rockers arms while spinning the push rods until they don't, then tighten the rocker arm nut another 3/4 turn." Well, every push rod seems to spin at a different, um, tightness. Does that make...

    Piston ring install issues.

    I'm FINALLY getting to building up my 94 350ci. I'm at the point where I have the piston rings installed around the pistons themselves and am trying to push the piston into the cylinder. It's gets about this far... and JAMS solid. I can tap the piston back out from the other side easily...

    Another aluminum head question.

    Alright, finally a question directly regarding a GMT400. We all know my junk by now... 89 RCSB 4.3L MT, swapping to a 94 5.7L and keeping the MT. SO! I'm making the swap to aluminum, NON Vortec heads. Anything has to be better than those junk smogger heads that came with the engine. I've...

    Fuel pump question..... Not a GMT400 but still GM.

    Sorry I keep posting non-GMT400 questions, HOWEVER, there's a serious lack of support (meaning no forums, and I don't do the FB garbage) for what I'm working on. Long story short, I'm converting my Wife's 67 Buick Special from a junk 2bbl carb, to a Holley Sniper EFI... in hopes of a very large...

    Right front takes a plunge when braking.

    I'll get right to it. Not a GMT400 but an 800. CCSB, 4WD. When braking, the right front dives like someone is pressing down hard on that corner of the vehicle. It does not pull to the right. The solution to that would be obvious, and I just put ALL new brakes on this thing not even 6 months...

    Instant orange peel.

    So, I was painting the front fascia of my Trans Am. It's made of some kind of hard plastic as opposed to metal, but I don't that made a difference here. The primer laid down fine. The 14 coats (well, maybe 3) of Rustoleum black laid down great. Then, this morning, I sprayed clear and got...

    88 - 95 V6 TBI distributor. Like New

    As the subject line says... I have a like new V6 distributor I need to get rid of. Bought from Amazon for a mint price and it has since dropped dramatically. Prefer local pickup but I can't imagine it would be much to ship this. Here's the FB marketplace link. V6 TBI Distributor And some...

    Will this harmonic balancer need a repair sleeve?

    Or not? I searched these forums and tried all of the common lying media sites, but I want GMT400's opinion. Behold.

    Timing mark unreadable.

    So.... I tried firing up the 89 4.3L last night to move it into the garage... and start my next stroke-inducing project. Negative. Cranks and cranks and cranks but no start. I'm not going into detail of all of the new parts I've thrown at this (due to age, rust, obvious bad parts...), but...

    4.3L to ?? swap.

    89 4.3L NON-Vortec TBI 5-speed, RCSB. I'll get right to it. I don't think there's much life left in that NON-Vortec 4.3l. Before anyone suggests it, there will be no LS swaps in this vehicles future, just because of the OBD-I to OBD-II wiring issues. That said, there are plenty of Vortec...

    Where is the timing bypass wire?

    89 4.3L 5-speed. Now that's out of the way, I thought I'd check the timing on this "no power at WOT" pos. I've been reading up and everyone says the timing bypass wire is behind the glovebox. There's nothing behind the glovebox except a blower motor resistor. The Emissions sticker on the...

    OBD1 codes 33, 34, 45.... and more great news....

    The title is complete sarcasm if that's not obvious. I put the finishing touches on my 88 (found out it's actually an 89) RCSB and took it for a test drive before surprising the inspection station. Never made it there. It was running pretty good until I had to go up a hill to get home...

    Bent pushrod, good compression??

    Yeah, I'm a little stumped, too. I was replacing the valve cover gaskets on my 4.3L and as per the norm, I give the valve train a once over. Well, cylinders 3 and 5 both had REALLY loose rocker arms. They seemed torqued down ok, but the exhaust push rods on those two cylinders were definitely...

    What are these connectors for?

    Once again, I had to bribe my Wife to let me use her phone to take pics. Can anyone name these? I think the first one (starting from the left) is a door jamb switch. Second one I have no idea. Third one might plug into the radio? Thanks in advance.

    Clutch master cylinder or slave cylinder, or something else?

    88 RCSB, 5-speed obviously, 4.3L. I think everyone knows that by now. I've posted this issue once before with limited responses, so here goes again. Clutch pedal goes down fine and releases the clutch fine. What it doesn't do is snap right back up. It's almost like the slave cylinder is...

    Why are there two different length parking brake cables?

    So, it seems there are two different FRONT parking brake cables... but they are BOTH for a Regular Cab Short Bed. Let me explain further. I was ordering a full set of cables from Rock Auto, and their site has a filter for things like front, rear, left, right... you all know this I'm sure...
