I really admire all you guys that can tear down and rebuild our engines, but for me, I have neither the skill or the best workshop for that. I’m confident though that I can bang my way thru a swap of my original 500 engine and gearbox for a rebuilt 650 and matching synchronized gearbox from a 126. I’m close to pulling the trigger on a fairly expensive engine/gearbox package from one of the larger vendors mentioned regularly here. (Brutal shipping and lost core charges to the US, but overall a bargain compared to many other collector cars. Plus, Cinquecentos are pretty rare and hold good value here). Package includes new alternator to replace the dynamo, 123 electronic ignition to replace the distributor and points, new carb, etc.
Anyway, just wondering if anyone who’s done this has any key “do” or “don’t” advice. I’ve been reading a lot about little snags that come up with the 126 swap (different heater pipe, longer starter cable, different starter, etc) and I’m trying to make sure those issues are covered. I also have some experience with the vendor selling the engine and gearbox and they seem to be a reputable supplier of good quality parts. (I hope that holds true with a rebuilt engine!) Any other words of wisdom or key things to do or avoid for those who’ve gone the same route? Thanks!
