Holley Sniper

[Green411]

I just had a look at some forums, including Holley's 'Sniper efi' forum. The administrator and senior members (ie the ones who know the most I reckon) generally seem to think that a dual plane intake is fine with a Sniper. My own experience supports that.
I'm no expert, and I'm a VERY long way from knowing a zillionth of what a professional mechanic/engineer knows, but I firmly belive that a successful Sniper installation needs to be in a car with properly matched engine parts on an engine in reasonably good fettle with a good battery and charging system. It won't fix basic errors in matching cam and heads, for instance. Then just follow Holley's comprehensive instructions, particularly about electrical connections, and you should be ok.
