Fuel Injection for a 340

Fuel Injection for a 340 - 07/17/20 12:12 AM

I work with a guy that has a nice 73 RR 340 Automatic car and he is interested in installing fuel injection to replace the Edlebrock Carb and make it more drive-able. Any suggestions on a good plug and play kit for the system? Mild street driven car so he doesn't want to go crazy on it but make it more enjoyable to drive on today's "gas".

Holley Sniper with a Hyperspark distributor will be the easiest EFI kit to install. I doubt that anyone makes an EFI gas tank for a late model RR so he'll most likely need to have something fabricated or else use an external fuel pump.

Just put a Stealth 4500 on my street car with a 605 Hemi...Like it so far.....Seems very flexible. I recommend the stealth 4150...

360 Magnum with full electronics and overdrive transmission for about 1/3 the cost and zero headaches of an aftermarket FI from the local autowrecker.

10 times the reliability, and 30 to 40 percent better fuel mileage.

Tell him I said "you're welcome". Better yet: 5.7, 6.1 or 6.4 Hemis.........but that's a seperate topic.

I've installed 4 Holley Snipers now, 1 being on my 440/512 stroker with the dual sync timing control. By far the best mod I've ever done to my car. My other 3 customers are also elated with their choice. Make sure to get the EFI ready fuel tank as it makes things clean and easy for installation.

The Sniper is the easiest to set up.. I went with the HP unit to make more power, I was gonna run
HP on my 416 in my Rampage for DW but I changed my mine and use the Rampage as my street rod

EFI Systems Pro has lots of good install and tech info on the Holley Snipers as well as some nice adapter cables and other accessories. If I buy another it will be thru them. Great guys and worth supporting in my opinion.

Thanks again for all the replies and information.

Rich, he may be giving you a call in the near future as he decides what he wants to do with his setup.

I'm a Megasquirt EFI guy but if I were to buy a throttle body system it would for sure be Holley from Rich.

why is it not driveable now ? I've got a 340 Dart and my 88 year old mother has driven it . In 12 years has not had a problem , sitting in 90degrees traffic or at the track , one thing that helped was an electric fuel pump freinds with mech pumps have a hard time starting and stall in traffic with todays gas . the gas today sucks .
