Update time
Beautiful day out today. Opened the garage door and spent a few hours working on the Tunnel Ram, carbs, and hood of the SC. The hood isn’t original and is already rough so I don’t feel bad cutting it more. I’m ordering tires today for the slot mags. And ordering a bunch of small parts to finish up the install of the carbs and stuff. It came out pretty good. Thanks for reading. Should have another update soon. Including installing the headers. I can’t wait to take this car to Kenosha in July.

2nd update today
Back in November at MCACN I picked up a set of used Doug’s D103 1.75” headers. They’re ceramic coated and almost 1k new, I picked these up for like 200 bucks because they’ve seen speed bumps a few times. But for this car they’ll work perfectly. After pulling the manifold off the drivers side the header fit right in after a little jack magic and a few choice words. I used copper SCE gaskets and ARP bolts so hopefully I don’t have any leaks. The passenger side was a bit more of an adventure because I had to remove the starter, partially put the header in, slip the starter in, then hold the starter up near the block while sliding the header further up. Another set of hands would’ve made the work easy. But Marty can’t do that yet since he’s only 2. So I had to make do with it myself. After many more choice words everything was installed and tight. Tomorrow I need to make a parts store run and I’m waiting for some Amazon stuff to finish the intake. Thanks for reading.

Small SC360 update
Working through a couple of issues with the headers. And I’m at a point where I could put coolant in it. Luckily it seems like I have no leaks. Had a small leak at the thermostat housing but a little permatex 3 fixed that right up. Otherwise I’m trying to finish a bunch of small things and I cleaned the slot mags today to have Costco install new tires on them on Sunday during our weekly shopping trip. Will have another update soon.

Small SC360 update
When I bought the car it had old American Racing Slot mags on it. I decided since I want to use the car this year I’d get new tires mounted on them. I also found NOS hub covers for them. I still hate the look of radials but I didn’t feel like spending 1200 dollars on bias plys so I spent 750 on new T/A’s. The headers are finally done and the new mini starter is mounted. Just need to finish up the wiring and it should be ready to crank. I bolted Purple Hornies to the collectors so it has mufflers on it. The throttle linkage is kind of done. I cannot for the life of me find a throttle linkage bracket that lines up to the stupid Edelbrock carb. I already hated Edelbrock carbs and this issue isn’t helping the matter. I still have some wiring to finish up and a bunch of small tie up work. But I think if I get a nice day or 2 I can have the car running again. Thanks for reading.

Seems like with your talent, you could make up a bracket for the carb. I start with a solid piece of cardboard, like a cereal box and start cutting, bending, and imagineering what I think I want until a shape starts to reveal itself and refine it from there, often, it's nothing like what I first envisioned. Some days, I use up all 4 sides of the box making "prototypes" and it may take a few days of letting the shape materialize in my mind to get where I need to be. Keep an open mind and let the shape become what it needs to be, not necessarily what you "think" it should be...

Looks good, and it's coming along well.
I wanted to get BP N50's for my Camaro, but they're obnoxiously expensive, so I have BFG TA's as well but it just isn't the look I wanted. I may go from 295/50's to 275/60's to get more sidewall height, we'll see. I had to figure out how to make my dual carb linkage work with the GMC blower as the linkage I had with my old tunnel ram just didn't fit. I went with a throttle cable and a kit from Summit. I had to make some changes to make it work (bending turnbuckles primarily) and it's not perfect, but it works pretty well. With the rounded sides of the GMC blower, there needs to be a way to make the linkage "bend" around the blower sides so I made a plate that mounts down by the base of the blower. The linkage can bind at WOT, so that's a bit disconcerting and I'm trying to resolve that now. I never thought of doing a setup like yours where the cable is mounted up high with a straight shot to the carb throttle arms. May have to see if that will work for me to eliminate that possible binding situation.

Had a little time today and then decided to run errands with the 360. I beat this thing like a rented mule. It’s a blast. The tunnel ram runs good. After getting fuel close to home I had to run back home to fix a few issues. The right side valve cover needed the bolts snugged up. I put a spacer on the starter as the drive was lightly touching the flywheel, it needed another throttle return spring and I had to clearance the hood a little because when the engine torqued the throttle got stuck on the hood. That was fun to find out.
Ran and got all-thread and cut it to put air filters on, then drilled the hood and mounted the Grump Lump. It’s ridiculous and I love it.
