Also have to consider, i tow maybe 5% of the time. Most of the time my daily driver is me cruising around empty, 30 minute drive to work...

I've gotten bashed pretty good about my 350 choice, but honestly for me, it works.

I say go for 350 and I'd be curious to see what it'd sound like through a 4 inch exhaust. And yes I have to agree with you i was so glad to rid my dmax for my truck. But good luck! I'd come help ya but idk how far you are from me.

I might have to take that diamond eye off and put it on my white 6.5 and run true duals with flowmasters on the red truck.... my old 454 had straight pipes, no mufflers and it was just obnoxious after a while. I want to hear a nice rumble, but not overly loud..

And i'm near bloomington. There is a truck meet in springfield in April that i'll try to have this thing done by.

Yeah, i'm thinking ether true duals with flowmasters straight out the back, or 3" duals into a 2/1 muffler then have a single pipe exit on the passenger side with a tip.

Not exactly sure yet. The more i've thought about it the more I don't think I want to hack up my 4" diamond eye, that was a nice kit, barely used too.

I don't blame you a bit on that. But I've hijacked your thread long enough lol. I'll have to pm you sometime since I'm from il.

Last night begun to prep the engine bay for the gas conversion. A carb'd 350 won't require hardly anything from a wiring standpoint. However, I did want to make sure that I retained all factory gauges, and that the factory heat/AC and light circuits all continued to work.

As far as the circuits that the 350 will need for the gauges, I will find a way to re-use the Oil Pressure Switch, (not sure where it goes on the 350 yet,) And i'll also find a way to re-use the temperature sensor which was on the drivers side cylinder head of the 6.5. My TPS, AC, and Alternator circuits will also get re-used on the 350 motor.

The big concern for me was the glow plug circuit. The glow plug circuit contains a heavy gauged 12V power wire from the junction box, and a sender wire from the cab, which splits off into the 8 glow plugs. They're a crucial point in starting the 6.5 diesel, so that's a solid 12V that would be a very "HOT" wire that I wouldn't want just laying around the engine bay, so I wanted to make sure to completely remove that circuit all the way back to where it enters the cab.

Easiest way for me was to just sit in the engine bay and cut back all the wire loom and remove what wasn't needed...

Now as far as wiring...... I could have removed the dash, and traced every wire back from the dash to the engine bay and removed everything that wasn't needed. However, I didn't want to disturb any of the factory harness, as I still need things like the heater module, gauges, AC, lights, radio, etc, etc to work.

When I swapped from electric injection to mechanical injection, I just used sealant and then electrical taped the sockets shut for any excess circuits. Then I zip tied them out of the way. Yes this will result in a TON of excess wires under the dash that essentially do nothing, BUT. By pulling the diesel oriented fuses and power wires from the junction box, i'll make sure all of those circuits are dead.

I'm not too thrilled about all of the excess wiring, but I just really don't feel good about further hacking up the factory harness risking shorts and other electrical issues down the road.

A little update. Been playing with some different front end combinations. Bought a GM Black/Red Bowtie and got the smoothie bumper bolted on. Also ended up giving the truck a nice wash/buff.

Definitely going to keep the smoothie bumper. Probably will end up having two grilles to switch out. A "GMC" grille with a custom bowtie setup, and then the Chevy with the billet insert and black/red bowtie.

Probably could've colormatched everything, but I've looked at a few all red GMT400's and I just don't really care for all that red, especially on a CCLB. If it were black, green, or something else I would color match everything on it. Overall the red/black provides a nice contrast of color especially with such a long truck.

I like the GMC grille/Bowtie, but I agree, it's just too much red on it.
Can't wait to see this all buttoned up.
