Engine rebuild cost
This will be my first time having engines rebuilt and I am looking for ideas on what it will cost to have someone rebuild them with top quality parts. The engines are 96 502MAG MPIs. I would be interested in what it would cost to just rebuild the 502s and what it would cost to go up to 540s at about 600hp each (could be carb or fuel injection on the 540s)? I am guessing right now from what I have read on here about 5-6K per engine.

How many hours? Why the rebuild? If you have low oil pressure, a knock, or bad compression then fine. 502 mags can live about forever. If you just want to upgrade then ok. A 540 is about 4500. 502 rebuilds 3500.

This will help give you an idea of what it will cost to upgrade to 540's.

Thanks. I was ghoing to call them as they are only a few hours down the road from me. I have a friend who does all my work and I am going to see what he says as well. I am not sure if his shop does engine rebuilds though.
Right now my engines have 360 hours on them. My port motor has a loud metalic knock which we think might be my exhaust manifold gasket. The engines are going to be getting pulled for new Exhaust (Stainless Marine) so I figured since they are out I should either refresh, rebuild, or go bigger. I would not mind going bigger and N/A if I can get the 600Hp out of them.

We are going to do a leakdown and compression test when we pull them. I will know exactly what I need to do based off that info. Just trying to crunch some numbers so I can figure out how big of a dent I will put in my spending account.
Thanks

360hrs on stock 502mpi's is nothing though. I wouldn't waste any $$ doing stock rebuilds as they should be good for at least twice that many hours. The only thing to maybe consider is to do some leak down tests and maybe valve jobs and head gaskets.
I saw the AETCO ad. I would do the option of giving them my block and going with the 650hp choice for about 9k if I went that route. I really want to look at building them into 540s with top parts and getting at least 600hp from them. So far the cost to do that from what I see is around 6-8k. I am just trying to get a good ballpark number for upgrading to the 540s with top of the line parts.
