    Upgrade order

    Also, quick question for those that use RTV on the china rails as opposed to gaskets. How long do y'all let the engine sit after installing the intake before firing her up again? Y'all wait the full 24 hours before fluids and startup?

    Upgrade order

    Thanks for the reply. I'll do my best to answer: When these plugs were installed, I had a pretty significant exhaust manifold leak that was fixed (headers) about 100 miles ago. Additionally, I lost an ignition module literally the same day I installed the headers, so there might be something...

    So, here's a pick of the plugs (I think I attached it correctly). Opinions?

    Howdy y'all!! Sorry I bailed on you folks. I promise, it wasn't intentional. These crazy times we live in require me to get out and travel quite a bit these days, and access to the interwebs is danged near impossible. So it looks like I've got a few unexpected days here at the house, so some...

    Double Hump thoughts:

    You bring up a good point. I've been tempted to go with vortecs, but have always shied away due to the cracking issue. If the summit brand vortecs have been re-engineered with a bit more meat, as you say, is the cracking still an issue that I'd need to be worried about?

    Finally got some time to tinker these last few days. Wife worked on restoring the dash while I de-smogged and added headers. Also put in a new headliner! So with the headers installed, she seems to have a touch more grunt, but I always knew that I wanted to do a bit more for her. I'm...

    What have you done to your square lately??

    Also removed smog equipment and added headers. I'll be cleaning and keeping the old stuff. She's a lot cleaner looking under the hood now. I'll post some pics after I get the engine bay cleaned up a bit...

    What have you done to your square lately??

    Wife and I decided to tackle the nasty cracks in the dash. Cut out the bad parts, filled with foam, cut and sanded to contour, filled with reinforced bondo, sanded, coated with shaky can bed liner, and threw some paint on her. Just need to come up with final color and add my 3D printed speaker...

    Double Hump thoughts:

    The accessory holes (or lack thereof) is what really sold me on new heads. As well as having to potentially work them over to match my needs. Thanks!

    Double Hump thoughts:

    After I posted this, I was thinking the same thing. Just too much trouble. I've had my eye on the 152123s for a while now. I'm thinking that with those heads, and an 1103 cam, it should wake this 68,000 mile motor up at bit. How does that sound? ;)

    Double Hump thoughts:

    Found a set of rebuilt double hump heads (casting # 3782461) that I can pick up for 400 bones. I've been toying the idea of getting a better flowing set of heads to go with a RV torque cam for my 83 K20, and thought this might fit the bill. What say y'all?

    Lost an ignition module. Why?

    Actually, it's an aftermarket Amazon special. I know, I know... But it was red, and that adds like 8.57 horsepower, right?

    Lost an ignition module. Why?

    Well, still driving on the back up ignition module, but all seems well. Bout to head out for the backup to the backup ignition module, but a pretty healthy test drive shows she's happy, so I'll not worry too much about it. Probably going to check my AFR with vac gauge here in a bit. I put...

    Lost an ignition module. Why?

    The bushings looked good as well. Like I said, mechanically, it looks brand new in there. I'm just weirded out by how much vac advance I'm getting.:/ So, I got some numbers. With vacuum advance disconnected and plugged, I get the following: 800 RPM - 12° 2500 RPM - 31° With vacuum...

    Lost an ignition module. Why?

    Thanks, but I have a back up ACDelco unit that I have laying around. Also, regarding the weights, they looked in perfect condition. No rust, good springs, etc... Thanks!

    Lost an ignition module. Why?

    Okay, so I've got a new ACDelco ignition module on the way. Until then, I thought I'd check the timing. I disconnected vacuum advance, set it to 12 degrees. Good baseline, and she seemed to like it. Here's my concern: When I reconnect port vacuum, I'm seeing an increase of 18 degrees at 800...

    Lost an ignition module. Why?

    'Preciate all the comments folks. Looks like I'm in the market for new ignition module(s). I too, believe in spares. lol As I mentioned, purchased an Amazon special, found here. Turns out a few other folks have had the same problem I did. lol If I replace the guts inside (coil, module)...

    Lost an ignition module. Why?

    Didn't have any compound, but the old one I put on had some. I know it's not the best, but it's what I had for the moment for troubleshooting. I'll grab some and apply it before I run her again. That being said, she fired up, so I know that it was the module, but she seems....sluggish? Also...

    Lost an ignition module. Why?

    Actually, they did. Drove for another 45 minutes after, if that makes a difference?

    Lost an ignition module. Why?

    So, I got the headers installed and welded out. AWESOME! Lost an ignition module on the way home from the exhaust shop. Super NOT awesome. I checked voltage at the dizzy. All good. I thought it was the coil. It was hot. And when I say hot, like the surface of the sun hot. I figured it...

    Exhaust Manifold Removal for Headers Install Questions

    Also, has anyone seen the episode of Engine Masters where they discuss the length of the header collector extensions? They tinkered with varying lengths of the extensions and dyno'd after each shortening of the extensions. What they found is that, while the changes in extension length didn't...

    NECESSARY Q-jet vacuum lines needed

    Thanks for your replies! Trying to get some pictures uploaded now, but I think I have it figured out. The diaphragm in the back I was referring to is the rear vacuum break. I was concerned with what type of vacuum it needed, manifold or ported. Decided on manifold. The thing was, there...
