Thread: My 1984 K10 - LM7 swap!!

Heavy duty trucks, those being 2500 and 3500 were still cable driven from 1999-2002 and 2003 was DBW.

If you want to get really technical they still used cable throttle bodies all the way to 2005 in the heavy duty vans. The express and savana vans stayed cable for much longer and those computers had special IAC drivers on the circuit board. Lots of people will actually switch back to cable if there drive by wire truck had a computer with the drivers built into the computer board.

Kidding, I just heard poor people and junk so I raised my head. Drive by wire is like smiling in a photograph, evil. Haha. I got to thinking about my friends' rides and dang...can only think of one other person still running a carb. I must have been asleep when EFI happened.

I understand why some people hang on to their carbs. Stick with what you know. I'm not mad at a guy for having a shiney Edelbrock 4bbl and air gap intake on his/her crate 350. HOWEVER, if you put a carb on an LS motor, I feel like you just traded a touch screen tablet for an abacus. (I can hear some crusty old guy in the back yelling "An abacus never runs out of battery!" Thanks old guy....)

Now that you say that, I DO WANT TO! And I might do something like that in the future. Right now, it'll just be the analog gauge on the rail. On the next build though...

BTW, keep the driveshaft! On the K10, if you have the other side of the bed cut for a gas tank, you know all you have to do is flip the brackets on a stock tank and you can run two? I did on my 75, Dad had gotten a newer bed and the fuel door was on the opposite side. The place cut the spot for the stock screw on cap. Having bought a parts truck, I chose to add the tank with a electric change over valve and hooked up the gauge to read which ever tank was feeding the engine.

LOL. Yeah, I got the driveshaft. Unfortunately, the right bedside is not cut for a fuel door. There is the bump in the floor for the hose clearance though.

This thread has me wanting to build a truck

I'd be really interested to see that build. I really like the way you approach and solve problems.

Isn't the "Holy grail" PCM, a DBC (with IAC drivers), 2 (maybe 3) bar, and flex enabled? I haven't played with boost or flex yet, so I'm not really up to speed on all the different PCM configurations.


Got my header bolts and 3 wire coolant temp sensor today.



Promptly mounted the headers which, I'll admit, was a waste of time and space but I love that look!



Okay. Everything I had on order has now arrived. NOW the build is on hold.
