So now I see the new FiTech dual quad 2x4 Go EFI, and I am wondering if that would be the best of all worlds???

Any opinions on my above choices, or is there something better for my 605...as it should be able to provide 800-900HP, Solid Lifter Roller Cam, 290/298 @ .050 and .700" lift. 12.5:1 CR.

Thanks for your advice, Mark


You are not going to get 900hp out of a small runner intake, that is for sure. Just not enough volume to support that kind of hp on one of those. At the very least, get the open plenum dual quad...I believe the Stage V is the open one, but there are dual planes out there, stay away from those.

I have not looked at the Fitech stuff, but efi that self learns and can keep you in your target afr will be best. I have run FAST efi in the past and like it a lot, and the Holley efi seems to be even better based on people with experience with both. The big hemi will like fuel....a lot of fuel!
