SO the engine in this thing is pretty ugly. The saddles and caps for the overhead cams are pretty scored up, as are the camshafts. From what I can tell it's had no more than 3 oil changes in it's 190k, so the buildup on the heads is ugly. I can blow chunks off with a air hose.
1k for a set of rebuilt heads with all valvetrain. Pull the bottom end apart, clean, surface, bore or hone block, HV oil pump, pistons, bearings, ect. Another 1k ish. Junkyard engines are 2k plus, so that's out. I'd rather put that into rebuilding.
Engine is coming out no matter what at this point. I have a Destroked 12v-5.4 adapter. I think I'm going to bolt that to a bare 12v block and sit it down in there to see what things look like. A 250-300hp non intercooled (due to lack of room) VE'd engine would do everything this thing needs to do.
