Opinions - What would you do - FI or Diesel ??????

[Mr.Chevy4x4]

Here is my quandry. I already have a 330 horse 350 in my K5. I also have a TPI setup but would have to buy the $400 intake to make it work with my Vortec heads. I would also have to buy a $300 wiring harness, and other odds and ends.

On the other hand I have a very low mileage(read under 1000) 6.2 liter diesel and all of the parts necessary for its install. Along with the HUGE radiator that came in the diesel truck.

Now, for a rig that is going to see very little street use, and a whole lot of trail use which one is better? Which will I be happier with? Opinions?

You can see my trucks specs in the signature. I have 4.56 gears and am about to step up to 39's.

Thanks,
Mike

Fuel injection, hands down. /forums/images/icons/wink.gif

<font color="blue">What year is your TPI setup? I would go with the TPI. The deisel won't make as much power as the 330 HP 350 with the TPI. If you use a junkyard harness like I did, you can save a lot

Sell the diesel, use the money to put the TPI on the HO 350! /forums/images/icons/cool.gif

Go FI and sell me the deisel...I hate on board computers./forums/images/icons/smile.gif

So did I until the first time I stomped the loud pedal with the TPI under the hood! /forums/images/icons/wink.gif Yowsa!!!! /forums/images/icons/shocked.gif

Well going fast with a SM465 is an exercise in futility and off road is more important to me. Getting good fuel economy is never a bad thing either. The diesel will lug better and also run at any angle. The only way I'd not consider a NA diesel is at higher altitudes, but I live at sea level so that isn't an issue for me.

I am looking for a rusted out diesel 'donor'...I considered converting to propane but the tanks are the big stumbling block. There aren't very many tank locations that are viable in a K5 and the common locations leave the tank vulnerable to rocks... /forums/images/icons/shocked.gif

I've got one out of a '90 Vette with the speed density setup. I am leaning more toward the TPI.

Thanks for the input.

Thanks for the input Harry, I think that is exactly what I am going to do!

<font color="blue">Mine is a speed density setup from a 91 camaro. I have a really good wiring diagram, if you want me to scan it let me know

 

[Mr.Chevy4x4]

That would be super! I would really appreciate that!

Every time that you romp on the loud pedal, you'll be glad that you did! /forums/images/icons/cool.gif

 

[tRustyK5]

Oh hell Mike, the drive doesn't scare me any...it'd be another fun trip. Affording to do it is another story though/forums/images/icons/frown.gif

No question. FI all the way. You wouldnt be happy with the GM diesel after your small block.
