Sniper on a big block stroker

Guess it's working for you well enough but from what I've read on various forums using a dual plane intake creates distribution issues. Not sure exactly how to ascertain something like that is actually happening unless you had 8 individual 02 sensors... Did you remove the center divider? Are you using a spacer?

I ask because I have a low deck Performer RPM on hand but I'm not sure it's worth cutting up just to work with the Sniper. Looking into a Holley Street Dominator as well which is a low-rise single plane.

If a dual plane intake works okay with a carb then it will work okay with a throttle body setup like a Sniper. Next time you see someone on a forum saying a throttle body won't work on a dual plane intake ask to see their test data. A lot of people just repeat stuff they heard but they don't actually test anything themselves.

It’s the dividing wall.....now if you have a cut/slot in it, your good. My dads 440/505 has the Eddy Performer RPM and it does have the cut out.

rmchrgr, Its not what the fuel injection wants it's what the engine needs. My cam is quite small (217/225 @ .050) and fits well with the Performer RPM's rpm range as well as my head flow. I asked Holley about all this before I built the engine and bought the sniper and they said build the engine combo how it should be built and put the sniper on it. My RPM had a notch cut out of the plenum divider (which is designed in by Edelbrock). I also chose the Performer RPM because I wanted that shock(ish) look...

Oh also a lot of guys like to run a spacer with the Sniper to get rid of the whistle it can make at part throttle. I'm not running a spacer currently though, I like the whistle.

Thanks
