    Default Going Sniper EFI on a '71 Dodge 360, which intakes will work?

    Hi all. We've got a '72 Dodge (71 Chassis) motorhome we are converting to HEI, and ditching the Holley 2bbl for a Sniper EFI setup with a new 4 BBL intake. Engine is stock, with lower miles. What intake will work well with this EFI system? Going to get the 550-510K Master Kit. The Edelbrock Performer 2176 intake is spread/square bore, will this work properly? I don't want to buy an intake that's not compatible with this fuel injection setup. Thanks all!

    Use the appropriate intake manifold type & model for your engine application/combination.

    Hi Danny. Thank you for responding. Since the documentation requires a 4150-style flange intake, something like the Edelbrock 2176 I had in mind will not work, correct? It's a spread-bore style. Actually, it says square/spread bore, so perhaps there's an adapter plate? The 2176K seems to have the right square-bore pattern, shown here: http://www.jegs.com/i/Edelbrock/350/2176K/10002/-1. That is the style I'm in need of, correct?

    Yes, that should work fine. It's a combination flange (square-bore & spread-bore bolt patterns). I have the same flange on my intake manifold. Test fit your Sniper EFI throttle body on the intake manifold, before installing it on the engine. I would not use a spread-bore to square-bore adapter spacer. In some cases, THIS is required to seal against flange/vacuum leaks:

    Cool. Well, that's exactly what I've done. I don't think it's all going to go smoothly, but I'm confident in the end we will get there. I'll be back once the install starts. Thank you Danny.
