So i bought a 4 barrel holley sniper efi. It way bigger than the stock intake on a 12a. Is there a adaptor plate i can get to fit it? i know i can buy a racing beat intake but id rather not spend another 400.

I thank you for your time and help. - kaden

You need to get the intake manifold designed for a Holley.

I've contemplated doing the same setup. It may necessitate a custom 4 barrel plate adapter. Or, search Mr Gasket, Edelbrock, Holley for adapters that might be close enough that it only needs flange holes for the mounting fasteners. Maybe some massaging. Getting those dimensions might be time consuming.

Are you going to run the sniper linkages progressive or synchronous?

 

Buy the RB manifold and be done!

 

There's no point to a Holley with the stock manifold, it's about the same size as a Nikki internally.

It's easy enough to buy a Holley carb spacer and turn it into an adaptor with some drilling if you still want to go for it.
