I am in process of building a 1970 B Body that I will drive - all over the place I hope ! . . . 360 with about 9.5:1 pistons, 1970 340 type cam, 727 auto and 3.23:1 rear end gears. Question I ask myself, is : should I go the route of fuel injection ?? You can get great products now, that you don't even need a return line ! They learn and then you just get in and turn the key. Granted it is about a $2k touch !!! That could pay for a lot of fuel with a carburator !
However, putting 10-15k miles on the car in a year, the ease of operation with the fuel injection would be appreciated - idle, start when cold, cold drivablity, etc. . . .
What would you guys do ?? I am good with a TQ for the 360, but wonder about upgrading to the EFI . . . .
Thanks
Mark

I'd go efi, especially if it's a 4 season car...I wish I would've put EFI on my DD before kids when I could've afforded it....my car is a bit of a PITA in the winter with the electric choke being somewhat finicky and winter blend gas...
I'd probably start with a magnum 360 and use the '96-up JTEC computer with a tuner.

What happened to the company that had EFI units that resembled carbs on the outside.
Financial ruin?

I would go the TQ route .....with a 904 trans.
FI still is a PITA, expensive and does not work right all the time.
Not if he would use the factory ECM and a Magnum engine.That setup is bullet-proof as far as dependability is concerned. He could even use the A-518 O/D transmission for even better economy and drive-ability.
That's what I'd do for a driver. Not the max hp setup, not the hardest/most expensive setup and pretty hard to kill.

For as mild of a 360 as you want, you should swap in a 90's magnum 360 and run it off of the stock ECU. You can still rebuild the engine and have the cam reground to be a little more aggressive like the stock 340 cam. Swapping in the stock electronics won't cost you much and ideally suited to an application like this.
Injection is so much nicer than a carb, I wish I had injection on my streeters. Sure would be nice when driving in different alititudes and not have to change jets.

I've been batting around the idea of running an early 90s TBI set-up with a Megasquirt system on my 318 Coronet. Depending on what the JY parts cost I could probably have a working system for under $600.
No longer taking $h!t from anyone!

If you have the money,and you are not good with tuning carbs,then yes go EFI. Me personally,I like to work on my cars for fun,and carb tuning is one of my favorite things to do. It cool to see the diff from changing one little thing. You pretty much only have to mess with a carb(once tuned right initially) if you are changing elevation and/or weather change,and at that it is usually just a jet change.If you get a wideband a/f gauge it makes fine tuning a carb very simple.

IF I want to run a carb I use a ThermpQuad, easy to tweak and they just work when right, especially if you go with the 9800 aftermarket ones with the electric choke setup. The one on my Dart has sat for 4 years and I started it finally after a few years of setting. The accelerator pump was stuck but with some WD 40 and a few pumps of the rod it was AOK again and started running great, even on that old gas in the tank, even did a quick burnout in the driveway after everything was up to temp and working smooth again.
If I wanted max drivabilty and MPG I'd definitely go EFI, but like said many after market setups are way too spendy and you have to modify stuff to make it work. Some of the stock stuff and the later 360 factory stuff can can probably be done cheap and mega squirt and others might be a option if you want to go low bucks and aren't afraid to make things and do it yourself.
Simple, go TQ, more complex but maybe worth it EFI.
