Hey guys I'm looking for some input on my next carburetor. It's a 66 Satellite with a 354 poly stroker. 3.58" Scat forged crank, Scat rods, Ross pistons 0.065 over, 10.8:1 compression. Poly heads with a little bit of porting, 1.94"/1.60" valves, Schneider solid lifter cam 264F (220° at .050, 0.450 lift). Topped off with a factory cast iron intake and currently a 1850 Holley 600 (vac sec). It's got headers, stepped from 1 5/8 to 1 3/4, 2.5" dual system.
Car is auto, 3.23 rear, used for hot street, cruising and at the track say 6 times a year. Weighs 3,640 lbs.
The car runs great with the Holley but I'd like to try something else. I've also got a 700 double pumper that I swap in and out and the car feels faster with the bigger carb (and made 7hp more on the chassis dyno, 341hp at the wheels vs 334hp with the 600) but the 600 is better on the street. I'm going to try the double pumper at the track early next year to see what difference it makes there.
There's so many choices my head's spinning.
I wouldn't mind trying an Edelbrock AVS2 but should I go 650 or 800? Normally I would think 650 but with the annular boosters would the 800 still work ok?
Or maybe a Holley 670 Street Avenger v/s?
Or a 650 double pumper?
Or a Brawler 680 v/s BR-67317?
I was leaning toward a 625 Street Demon but the reputation for poor build quality and a few design issues is putting me off.
Then there's boosters: straight, downleg, stepped, annular...man there's some choices out there.
I'm wondering what I'm leaving on the table with the 600 1850. I'd like the same reliability (super reliable), better low end and midrange, and maybe some more at the top (so basically more everywhere haha).
Any advice appreciated - I realise this is a very open question and one where brand loyalties are strong.
