Off topic here, sorry...do you guys remember going to a junk yard and getting performance parts?  4 barrel carbs, posi rear ends...  Now the best "junk" yards that carry that stuff sit on my pc desk and are only a couple clicks away.  I used to love digging for parts, ah the memories.

 Yeah, we brought our own tools and the shipping was WAY WAY less expensive. The bee stings and chasing rattle snakes was not much fun, but the stuff we took home ALWAYS fit.

I used to work in a "Wrecking Yard", as they were called back then. Now they're "Salvage" yards. WhatEVER...lol I had access to any part I needed, for whatever car I needed parts for....and they were dang cheap, too! lol I weren't all that excited about crawling under a car with a cutting torch while fighting off rattly snakes, and Black Widders, but I learned a LOT about a lot of different kinds of cars from there. With that said...let's try to veer back to the actual topic....lol.

Shoot, I thought it said Holey Quadrajet. So much for the Batman reference.

LT-1's had a Holly 4150.

I knew a guy back in the 70s that put a Holley spreadbore on his SBC and he said it had all of the bad features of a Holley and none of the good features of the Q-jet.
