Very cool Mike! What kind of carb is that?

I remember doing the same thing (learning carbs) on my V8 Fiero project a number of years ago. I rebuilt a 750 cfm Rochester Quadrajet for it. My brother called it a Quadrabog lol. The 305 sbc came out of a stock car and the carb came with it. Rebuilding it was like having a clock apart. But it worked beautifully after rebuilding and tuning. I eventually realized that for the street application, it was too big for the engine cfm wise, and replaced it with a 650 Holley "double pumper". Good memories!

As for the reasons why a carb on an LS4? I'll can add that hearing the sound of the secondaries opening up behind you on a V8 is totally an experience not to be missed. I'd like to hear that when you get it all together.

P.S. The memes made me laugh as well.
