318 to 350
« on: February 11, 2020, 06:59:51 am »
I have recently cooked my 318 and am thinking of installing a 350 chevy with the 400 turbo. To those who have done this install,what year of truck engine do I look for for thatís fuel injected but without all the pollution apparatus.

You would probably be better off putting a 4.8, 5.3 or 6.0 vortec engine in. More power and easy to find. You'll still need a wiring harness, computer, fuel pump and regulator, also a proper flex plate and spacer for the th400 to mount to the block. There''s other options such as electric fans, drive by cable or wire (electric gas petal) and having your computer configured to what transmission you choose. You could also put a carburated 350 in as well, but you asked about fuel injection.
I'm not trying to discourage you and think its a great idea. There's a few things involved in installing fuel injection in a bombardier. I've done it and it cost me quite a bit of money but love the result.

I am hoping to find a truck at the wreckers or salvage yard that would have a complete engine,tranny,wiring etc. Just not sure what year would be best suited.

Both the 318 and 350 are good choices, I have them in a hard working environment. Staying with the past is always an option when doing some of your own work on the machine. In saying that, my neighbor installed the Holley Sniper Kit on his Chrysler 360. Says it works well. Car club enthusiasts around home are also moving to the Edelbrock AVS2, a regular carburetor with a new style fuel delivery. Both have excellent professional videos to watch. Nothing wrong with a new fuel injected motor either. Good Luck !

2wd trucks are harder to find with the combo you want, but not impossible. Look for the 3/4 to 1 ton vans. They are usually equipped with the TH400 or 4L80E transmissions to the engines you want already. I'm running a 6.0 LQ9 engine with either a TH400 or 4L80E transmission. I have a separate computer programmed for either engine/transmission combination. You will also need to modify your harness to work in the bombardier. I got lucky and found a guy who made the harnesses for the bombardier's in Yellowstone national park.
