Has anyone done this? I found an NPR w/ a blown motor that is set-up for lawn maintenance. Any idea what it would cost for someone to replace the engine?

IF the head and the intake are still good; then you will be looking at around 2000 to have the block replaced with a good used 350 block. 2500 if you rebuild the block youself then have it installed.3500 if you have a new shortblock installed.

What type of engine?

Common V8 Gas engines can be bought for about 2K ( maybe less ) with exchange. You have to move the Alternators and stuff from the old to the new. Buy a New Pump, repalce the engine mounts.

I would say around 3,500 to 4,000 for sure depending on the amount of new parts and hoses you buy.

Check the Radator for oil and crap. It may need to be flushed out.

It is chevy 350 in a '99 NPR w/ 16' lawn maintenance bed for $3600. So possibly $4k to make the thing run like new? I am thinking that could possibly make a great reliable work truck. It probably would not depreciate much lower than $7600 either.

Chevy V-8 Vortech engine rebuilt on the Internet for less than 1500.00.

Find local specialty shop if you are in a major market and you can get one for around 1000.00. Then you are likely to get the whole thing done for less than 2500. Toss in another 1000.00 for the transmission.
