Ok, so I was driving the kit car last weekend, and unbeknownst to me, I developed a hole in the sump, lost all my oil, and the engine seized (ok by that time it was no longer unbeknownst). So, this weekend I went to collect a couple of spares. The first is a direct replacement, it's been stood for 10 years and has also seized but only from age. Apparently this engine was running well but using a bit of oil before it was removed. The second is a short block; also seized from age and very dirty, but has reinforced bearing caps. My initial plan was to swap my broken engine with the first one, free it up with some Diesel and persuasion, and run it for the summer, put up with the smokiness, and rebuild my broken engine with the short block into a decent, strong, mildly tuned engine over the winter. Now, I've been offered a third engine by a bloke at work. It runs, it's a direct replacement, but with Hepolite pistons, a stage 3 head, a rally camshaft, big valves, and twin 45 Weber DCOEs. It's also got a competition clutch and a Quaife 5-speed straight cut gearbox. ARRRGHHHH help me make the decision!
