Default EFI vs Carb

Alright im putting in a new motor in my car, 302 stroked to 347 forged internals & all kinds of other goodies. N/A for now thought. My car is a 1995 mustang sn-95 style. Would it be easier & cheaper to go with carb? Im thinking i wouldnt have to upgrade all the fuel rails & injectors and things like that if i just go with carb. Will it be harder for me to pass emmissions with carb? What all will I have to change to run a carborated setup. Im thinking that i will have to get a fuel pump that mounts on the block, instead of a intake fuel pump. If using a carb and putting out around 500 hp will i be able to use the stock computer with msd ignition 7 series box? Thanks Troy

screw carbs, youll never pass emissions with one, your gas mileage will also suck *****... just get it dyno tuned after your done, and youll be fine

+ 1 on no carb, i used to be a carb man until i realized how well the computer maintains the fuel system when running properly. i sure dont miss those nights either when the humidity would increase dramatically in louisiana at the track and the carb started acting stupid. one wrong adjustment and you might be done for the night during bracket races

Okay well if I go with fuel injected what fuel system do you guys recommend, what injectors, and what computer should I go with... Should I go with a 255lph intank pump, would that be enough? Any help is great. Thanks Troy

Well, I always advocate the Megasquirt stand alone engine managment unit.... I have it in my car.. and I love every second of it!

injectors... you could probably get away with 30#ers.... 36 at the very most. especially if your staying n/a 30 would probably be good, 36 would be a safety net

yes carbs are not as great as EFI but there a hell of alot cheaper. Ur looking at prob 1000$ worth of sh** just to get that motor running with EFI good tune,injectors etc. Carb hell 400$ and ur rolling! Plus you can sell ur computer and injectors and all other BS to cover the 400$ so u actually gain money.

but his car is already wired for EFI, and its a simple case of plugging a megasquirt in and changing the injectors...
