Whipple aux injectors VS marine intake build?

I was wondering if anyone has tried using the Whipple aux injectors without the Whippletronics to overcome the limitations of the Vortec spider injectors? Waht about using a piggyback management unit (emanage?) or secondary controller (http://www.splitsec.com/products/aic1prod.htm)?

I am using teh marine intake, if you use those extra 2 injectors with teh stock L31 vortec 350 intake, you are GOING to get horrible cylinder to cylinder distribution problkems. That intake is designed to flow AIR ONLY. Get a marine intake, The swap is easy.

Yes thatw orks very well also. It pretty much matter how good the persons fabrication skills are.

I like the MArime intakes because they look stock and are designed my GM, but the converted carb intakes probably make more power.

This is my most favourite marine intake manifold. The Scorpion Tunnel ram with 90 mm t-body.

the lower plenum and fuel rails

the upper plenum and t-body

This is the cross ram marine intake that I am using.
