CLASS RACER FORUM - View Single Post - Joe Newbie, 20 Builds a "Stocker"' in 2023

NB has been busy lately. He buys a gallon of pure white acrylic and hardener from Summit. The bodyman at work offers to spray the Chevy in his home spray booth

VR has been assembling the 283 during after work hours.

NB gets a cash advance on a credit card and buys a used open trailer from Craigslist

He takes apart his original 4GC carburetor and cleans all the parts.
He stops by VR's place after work..
Hey buddy, I found these pics on the net, The first one looks just like mine, but the second one is different down inside. What's legal to do to these things?

VR> Glad you asked. You used to have to run the original 66 boosters, or venturi clusters as they're sometimes called. The exact same part number. The ones with the small center hole in the pressed in tin horn..Now they don't check any of that stuff.You can use any booster that you might find in another make of GM car.
The only rules are the throttle bore size, the venturi size, and oh yeah, the boosters can't be "too shiny" .
There are some guys that are real good with these, like Deano, but I think you're doing the right thing by learning them inside and out. If you have to work on the carb at the track, you want to be familiar with them.

NB will be picking up his T 200 soon, from another racer that lives north of Phoenix. He does a great entry level transmission ;-)

We're moving right along now. NB might be able to test this thing in a couple of month, if Wild Horse re-opens.
