hi everyone I fired up my sniper efi yesterday and it’s running great. I’ll add a pic of how I wired up the 12v switched ign as well as a diff one to a toggle switch . Where it says “IGN” means to the Ign1/ign2 wires that were spliced together. And where it says “fuse” means to an always hot...

I have a red, orange, and black coming from my distributor. The black goes to ground. And the red goes to coil + and the orange goes to coil - There is also a brown wire on the coil +. I am told in the efi kit. I cannot hook any wires to my coil except for the 2 wire that tell me too

Thanks everybody for the responses and thank you 67dart. So I understand what you are saying about having to use both connected together. Sorry to sound really stupid but how do I go about “connecting them together? “ add 2 extra wires coming off the switch and into my wire from the efi kit? Or...

yes stock wiring harness. And ballast resistor is already gone. (Currently running a MSD RTR dizzy

BoingK. Thanks for a cam suggestion and dual plane is what I'm going with I will check at that cam and do some research.

Yes I am talking Indy aero head 587 heads and ok I will do that thanks!

Any how. I plan on sticking with switching to my dual plane intake but am wondering mostly on which heads to use or install and cam suggestions of any per setup thanks

Right now it has a torker 340 single plane on it. Thanks from what I been reading a dual plane will give me better low end and starting/ drive ability then a single plane which is more top end?

Right now my 1989 roller 360 is running stock heads( motor pulled from 1 ton ram van) which I believe are the 308 swirl port heads. Currently the motor has a eddy 650, single plane intake, hooker long tubes etc. I have a set of 587 Indy heads with the larger 2.02 valves, I am considering...

Hi guys I got the car a little over a week ago and don't know much about the tune or combo of the car I'm trying hard to find out more. Looking at the machine shop receipt for the head work it shows the heads are from 1973 and elsewhere it states a valve size of 1.74 not sure if that's exhaust...

What do you mean by combo and tune? Sorry I don't understand and the dyno operator did have cooling fan but the outside temp alone here in stl Missouri area was 97 degrees today super hot Had to leave car show to change my shirt! Lol thanks for response

Own a 1975 plymouth scamp with original rear axxle in it. The tag on the back of the pumpkin says 2.45 I'm assuming is the gear ratio. I was told the rear axle is a 8.25 or 8 1/4 axle does anyone know if that is correct or how I could find out ? I want to add some diff gears and some type of...

I have the new springs installed and it raised the saggin rear of my scamp a full 4 inches The car does sit slightly unlevel in the back about 1 inch difference exactly. But I don't mind it at all. I am very happy with them and suggest them to anyone. Thanks again everyone
