If engines are running as they should, with 25p props they should get to around 4500-4600 rpm and 64 65 mph as mine did which sold a bit under $20k with tri axle trailer just FYI

Ad states they are rebuilt but I have a feeling they have never been rebuilt and need a fresh rebuild on them. If the price was right I would still like to have the boat as it is clean, but needs some attention to get it to where I would want it.

Frankly, in a 27 I think you would be better off with small blocks. The boat feels well balanced and it is a piece of cake to get more power out of the small blocks than the 330 horse 7.4's provide. I couldn't imagine trying to work on a pair of big blocks in a 27 bilge as even my 31 bilge is a giant pain in the ass to work in. The only upside to the big blocks are bravo drives, but an alpha can swallow 400 hp if you are mindful of them.

The beauty of the big blocks is that because of the torque I had ,I could stay on plane at 2200 rpm and cruise along the beach effortlessly.

Couple of well thought out 377-383's (old school stroker) small blocks makes a nice combo in a smaller, skinnier boat like a 272

look at my posting about the 303 on ebay, might be something to consider, its awfully cheap, so check it out good if it checks the 303 is pretty sweet, little faster then the 272 as well, but I still would not shy away from a nice 272
