This was on my 74 Chevy G20 Van with ZZ5 350 SBC crate engine which I acquired from a friend who did a featured on an article on Chevy Magazine. It came 400hp/400tq stock but they reworked the heads, swapped out single plane intake, bigger cam and this Holley carb at Westech which Dyno'd 440hp/444tq.
I replaced it with dual plane intake and Edelbrock 600cfm for street. I've drained and cleaned the carb.
it should be pretty much plug and play
Below is a Link to YouTube video this carb was on
