Gt40 engine replace cost?

That ECM from the GT40 should bring some good money. Can't get those OEM any longer.

I'm interested in some of those parts when you get ready to take it apart.

Malibud, How'd you do on this one?   
I didn't see your post earlier about how the water got into the oil.   cracked manifolds will give you the water in the oil.   it's not a complete tell all, but is one of the ways the water can get in.      I did get lucky... but I went in assuming it needed a motor.   I paid little enough for the boat that I could put a motor in it and be below the market value by a good margin... people who don't want to mess with putting in an engine realize that they have reduced the value of their craft by a great deal (most of them).   if you are armed with knowledge of what it will cost to do the motor(worst case) and leave some margin for things you can't anticipate, you'll be fine.   if you can't get a DEAL on a dead boat, don't buy it, it won't be worth the hassle.   If market for that boat is in the 15k range, I don't think I would go more than about 6-7K. look on craigslist and see what people are asking in similar condition with a running engine, then subtract a bit from that, usually there is some negotiation room on the seller side.

Need more info, pictures would help. The chevy sounds a little tired for $2200

How much for the sport?

If it's just frozen as in ice frozen then that's no big deal. Just get another block and swap everything over. The GT - 40 block is the same as any other 351W except that it's already cast for roller lifters if you wanted them. Assuming its a 4FTE and assuming the water didn't damage anything else internally.
How much is he asking for it?

Going to call today . Keeping my fingers crossed that he still has it . I wish you were closer. Thanks Jody ! That's a huge help......

pressure testing manifolds

mine was the same... plugs out, manifold cracked etc... I was able to replace the manifold and that fixed the water in the oil problem.   the freeze plugs were about $20 at the local auto parts store.   get brass ones if you try it. I had to run it on the hose and change the oil a couple of times before I was satisfied that nothing was leaking in the heads.   if the plugs came out and the manifold is cracked, you can still be OK on the inside of the block... its possible both ways, so since you'll need new manifolds for a fresh engine anyway, it's worth trying that route first to see if the block is OK

how frozen is the question.   Plan on a new engine, and buy the boat accordingly.   Ski Dim has packaged deals that you can drop in if you are not mechanical, but there are definitely cheaper ways to skin that cat.     I purchased my 94 last year with at "frozen" block... I took the time to get the rotating assembly freed, put on new manifolds, carb and fixed some other neglected items and am happy to report that it runs great. I am guessing we'll have it in the water this summer with a fairly minimal investment.   The Fuel injected engines do come up from time to time, particularly from people like Jody at Fl. inboards who replace them for the upgraded speed control compatibility (?).   they are not common, but can be had for a ~3-4 thousand dollars used if you can find them.
