2019年10月2日 · It has an Edelbrock performer dual-plane square bore manifold and Holley marine version of the 4160 carb. It also has a one inch thick spacer that I don’t particularly care for and this sheet metal throttle cable holder that is wide-open. So it goes manifold, gasket, one inch spacer, gasket, throttle cable holder, gasket, carburetor.

Got a 1" spacer under the Sniper EFI unit on a Edelbrock RPM Air-Gap manifold, on a 351 Cleveland 4V closed chamber heads and a Comp Cams Muther Thumper cam (7" Hg @ Idle @1000 RPM). I'm having some running issues with starting, hot or cold, finally got it to idle, but still need to correctly set the TPS in gear (IAC is @ 100% in gear), set ...

TIP: Holley did testing with a 1" open spacer under their 900 CFM TBI unit, and it actually improved the air/fuel distribution and made 10-15 more horsepower above 4800 RPM. May God's grace bless you in the Lord Jesus Christ.

2021年1月23日 · One is an open spacer on an air-gap dual-plane that already had the divider cut, and it gained 8 HP on the dyno with a carb, so it stayed when the Sniper was installed. The other is a Victor single-plane intake that gained 18 HP when a 2" super sucker 4-hole taper spacer was installed, again with a carb, so it stayed under the Sniper install as ...

2024年7月19日 · The adapter/spacer is bolted on, under the Sniper 2, and is working fine. I'm sure it's not as good as a aftermarket Aluminum Intake Manifold made for the proper Holley 1450 footprint. As the "two barrel" stock Aluminum Intake Manifold it's more restrictive to airflow, but it's working and was really easy to do.

2018年8月23日 · Mainly due to safety reasons. I purchased a Holley Terminator EFI Stealth for my machine to go on top of a Edelbrock dual-plane Air-Gap manifold. After plenty of research I have come up with the fact to help my car run better, I'll need to install a 1/2" carb spacer.

2020年10月2日 · My approach was a little unconventional. With an open spacer it whistled. On my stock cast iron intake, the Sniper and/or engine didn't like the 4-hole spacer, but the whistle was gone. My temporary/permanent solution was to cut out the center section of the 4-hole spacer so each barrel was "seeing" each intake passage. Works great.
