Carb Adapter Help!

Hi guys,

I put a Holley Sniper on my truck. I love it but I am having issues figuring out what kind of adapter I need between the Sniper and my Intake manifold. The engine is a Goodwrench 350. When I install the Sniper and carb spacer or just the Sniper alone, a small gap is exposed up front which sucks in air. While the truck is running the intake will suck hard on your finger if you block the gap. I’m sure this is negatively affecting the system because the Sniper is compensating for an intake leak.

Can anyone direct me to which adapter I need for my given intake manifold? I ordered an Edelbrock 8716 but it’s not the right one.

Thanks for any help.

Jim
