350 vs. 6.2 diesel

Right now I have a stock 350 in my truck runs pretty good. I can get a 6.2 diesel for notheing and wondering how much more gutless or more powerful it would be over the 350? And I figured it would be alot more work to put the diesel in.

You'd get less power from the 6.2 in its stock form. It will get better gas mileage though.

Go pull a sparkplug wire on your 350. That's what it'd be like driving around with a 6.2L.

The first time you need to replace an injector pump you could've rebuilt a 350.

Re: 350 vs. 6.2 diesel

Thats true wrath, but how often does that happen? I honestly couldnt tell you but in the long run Diesels last long do to lower operating RPMs.

Also the regard of mileage has to come to mind. I have a friend at college with the same model truck as mine, except he has a 350 and I have the 6.2 He gets in the area of 10-12 Miles per gallon. I can pull 19 miles per gallon with mine. We both have similar driving habits. I have a turbocharger on my truck which I think would lower mileage some, also 31/10.5 tires which would lower it some also. His motor is still stock in terms of performance mods. He runs 235/75R15s. So the money saved on gas could pay for that injector pump.

If your looking for something to get alot of performance and horsepower I would go for the 350 before the 6.2. If your looking for economy I would go for the 6.2

Re: 350 vs. 6.2 diesel

A carbureted motor usually lasts around 100k... not usually longer due to cylinder washing. $700 to do a rebuild.

Most 6.2Ls were parked by the 150k mark, usually once the motor wore out after the injectors and pump were replaced 30-50k earlier. Sure, some last longer but some gassers do as well.

I get 16mpg on the highway/expressway with my 305 whether I run 235x75r15s or 33s. It's 9-13 in the city. I drive a lot harder than most people.

I've never seen someone put a 6.2L where a gas engine was. It just doesn't make sense. However, you do see 6.5L and 6.6L diesels going where both 6.2Ls and gas engines were.

Thanks for the info. Another question how would the 6.5 turbo diesel perform compared to a 350?

a friend of mine with a 93 z71 almost identical to my 94 said he was going to show my 6.5l turbo diesel a thing or two with his 350 tbi. after i blew his doors off from a dead stop to 90+ he traded it in on a dodge.
