So I read on the goblin website that they don't recommend a donor that has mileage over 150,000 my question is it just because engine will have to ber rebuilt or is there something else I'm missing. My thought is if I can find a donor with very high mileage for a good price I would buy a ldk motor from zzp and use everything else from the donor that would have high mileage on it but should not be affected to much by the mileage any thoughts
