I had an LS-7 and I ran one of the now obscure Holley 3 barrel carbs, I think the were 900 ish cfm and it ran well. Actually very well.
I've got a couple of them...both are the larger 1050 CFM versions. The smaller 950 CFM versions have normal looking boosters in the rear rather than the "slosh tubes" like the 1050 CFM version in the pic.
I ran one of them years ago on my 427 in my '68 Camaro. I switched the large vacuum can for a small "normal" one and told everyone at the street races it was a 780 CFM. It actually ran very well. The small can was a little trickier to tune but no big deal.
I drove one of those once! Probably mid 80s early 90s.
It was on a 13:1 L88 built up by Baldwin Motion nearby..
No idea how big the cam was, but it was a monster.
Aluminum heads, 1050 3-barrel and a stock T/A hood scoop.
Shifted into 4th at 120mph and got 20 feet of rubber in a 71 Trans Am street racer.
Somebody on Staten Island made a lot of money with that car. It looked 100% stock.
Until you started it.
The noise it made was a dead give-away you were in deep trouble!
It idled at about 1500.
If it didn't backfire and belch flame out of the scoop, or blow the mufflers off at least once a week.
Sold for $3200. I lusted for that car bad.
600HP at 7000 rpm is fun!
