Engine swap

My GM 3.0 is getting tired. There is ready availability of marine versions (Mercruiser 140's) in my area with low hours at cheap prices. Would a long block of one of these be a good candidate for an engine swap? Or are they different enough that I should just rebuild what I have? Thanks

Thank you for that, I figured as much.

A follow-up if you don't mind, what do you suppose explains the difference in horsepower rating between the engine in my lift (when new something like 50) and the HP of the marine engines (140)? Is that just a difference in how the engines are rated in two different applications or are the marine engines actually much more powerful?

I agree with Partsguy5. I always rebuild the original engine when that option is available. You never know all the little idiosyncrasies that makes your application unique until trying to fit an engine not configured to your application. It's all those little things which eat up ALOT of time & money

Customers love technology- until they have to pay to fix it!
No it would not.
A lot of the 3.0 that are used in the forklift industry have been modified to each OEM's application. Would suggest rebuilding yours or there are several rebuilders that offer rebuilt exchange.
