Comparing the 3 (holley avenger efi, powerjction III, and Atomic) The powerjction is about $350 less, with more of the stuff to go with it.

So if I jump on the powerjection kit, Do i need to upgrade the Distributer, plugs/wires? Should I buy a MSD 6a or 6AL box? <---prolly should anyway. HA! I guess I am asking what I need to buy to go along with the PJ III set-up?...

 

WOW! Edelbrock pro flo is slick, but friggin spendy! POW! Might as well swap the engine for that. HAHA!

 

Looks like Edelbrock joined the TB style with the E Street. Has bluetooth to connect to a inlcuded 7" tablet for tuning

 

Just finished installing the Atomic on my 65 very easy to install and set up.
Well worth the money.

 

I was reading this post with great interest.
I’m driving a 66 Mustang with a 347 stroker AFR heads and a vintage Paxton kit with a 700 Holley in an enclosure, and I’m seeing approx 550 HP.

I would like to know if the Powerjection III returnless system would supply sufficient fuel for that application.

Maybe the Holley http://www.holley.com/550-402.asp a better choice with all the adjustment options

The Edelbrock http://www.edelbrock.com/automotive_...pf_intro.shtml has the injectors in the manifold, is this not better for performance??

Thanks for any advise
