Easy to install, quick install time!
This is for my Chevy V8 350. Worked great right out of the box. Arrived quickly, Wasen’t to expensive and works awesome! WOT sounds great! Gives my exhaust a nice semi quiet ride. Would buy again.

The Demon
Bought the street Demon 625, and installed it on my 79 Corvette, 350 edelbrock performer intake. Fits perfectly, no adjustments, just idle speed. Out performed a custom built $600.00 quadrajet. Big difference, the tip in is very very smooth, and when WOT comes on, the goggle secondary means business puts you back in your seat, the front end jumps up, the rear wheels break loose, the side pipes roar and growl, and your gone. You better get the Street Demon 625, if you want to keep up with me

No tuning needed so far
I bought this carburator a few weeks ago for my 1971 ford f 250 Whit a 352 fe with hp 390 heads and s code intake and performance cam. cranked the engine over several times hit the throttle and fired right up. Works amazing great throttle response engine sounds better no big or flat spot under like my old Edelbrock 1406 did. Driveability is amazing I picked up gas milage to. The only thing adjusted the idle speed. It would be nice to have more options for a throttle return spring tho.

Simple and easy
Priced right for a proformance carb compared to other options. I needed a bit more tuning for my application so it wasn't quite right out of the box like others have mentioned. The only bad is the placement of the high idle adjustment on the choke. It's hard to get to and the only reason I gave it 4 stars instead of 5. Otherwise very happy with the purchase
