Im thinking of installing a complete after market EFI set up on my 72 340 w/manual transmission producing 450-500 HP . What are my choices and who makes the best and most reliable systems ?. Fitec, Edelbrock and Holley makes them.... anyone else ?.

A Holley Sniper with a Hyperspark distributor would be your easiest install. Holley will also have a EFI gas tank that you can install. Only thing you would need to do is add a return line to the car.

Holley has a returnless pump package now, so you only need 1 line from the tank

I am considering doing the same for my '72 340 manual valve body automatic car...anyone using FiTech's Go EFI (250-650HP) system on their cars? shruggy
If so..how do you think it works for you...pro's/con's??
I have a 16 gal. fuel cell in the trunk, and a frame mounted Summit 105 GPH electric fuel pump currently...3/8" braided fuel line from cell, all the way to the 850 cfm carb.I don't want to change the fuel cell out either, thanks as well for any input.

Holley Sniper
I have done a few FiTech systems with mixed results and had Good results with Sniper. Now that both systems are about the same price it is an easy choice. Spectra EFI tanks are not bad for the price, But the fuel gauge will be way off. Ohm range on the ones I used are not right for Mopar.


The only Carbs I care about are under the hood!

I have done a little research on the Holley Sniper master kit....multiple people complained that their kits came incomplete, even though Holley says everything is
included in their master kit. Why would I spend close to $1,300 and receive an incomplete kit from them, when Holley "supposedly" sells a complete kit??
Anyone here encounter this themselves? shruggy

Anyone who complains about something like that must not have bothered to look at the picture of what is in the kit before they pushed the buy button. The kit contains a lot of stuff but it might not be "complete" depending on your car and what other parts you have. I ignore people who complain about stuff like that since it isn't a mystery what you're buying. Just look at the picture. https://www.holley.com/products/fue...ter_kits_with_fuel_system/parts/550-511K

Another 2 systems are Megasquirt. They have many different systems. MS2, MS3, more and they are very popular for the do it yourself and very cost effective up front.

I have a Pro M on a fox Mustang. They also have a hot rod set up or universal system. It is a full management system. I can answer any specific question about Pro M. If you can imagine it, it can do it. It is a Mass Air system. Most are Speed/density.
