engine

well my truck came from the factory as a diesel but the previous owner put a sbc 400 in it now my question is if my sbc 400 gets warn out should i put the 6.2 diesel back in it or just redo the 400 i use my truck as a DD and every now and then i do a little vehicle recovery for money and some mud bogging

Re: engine

Why would you go through the trouble of putting a diesel back in it? If your not going to use it for any of the intended purposes of the diesel gives you then it's a wasted effort and you will be paying double (or more) in fuels costs.

There are many members here that have found ways to make the 6.2 diesel a good option for it's intended purpose. Using it as a DD is not one of them.

Re: engine

If you do ditch the 400, I want it...lol

If you're not worried about mileage, just torque, the only thing that will beat a 400 is a big block. and LS engines are expensive. 400's the best bang for the buck.

Re: engine

yeah . 400 is a great small block. one of the best in my opinion. It all depends on what ur after. Sounds like it suits ur needs but I can imagine your looking to get alittle better fuel milliage because it is a DD. Nice thing about the 6.2's is with an electric trans 4l60/4l80e you can pull 20 plus mpg but with the price now a days it is not worth it unless ur after the torque. 6.2's where never the best diesel out there but they did well in the fuel millage. I would run the 400 till it goes saving up some money then rebuild it better then stock into a 406. If your like me an LSX motor is not an option money wise.......

Re: engine

Like Bob says, stuff a fresh 350 in it and go. It's quick, easy & pretty cheap.

Re: engine

Start with the basics. Get a "good" tune on the motor and carb. Find someone that "really" knows carbs and have it adjusted properly. Make sure you have a quality air filter in your breather. If you don't have a K&N get one. Convert to a clutch fan, or consider electric fans.

What gears are you running?
