All our engines come with a 90 day warranty unless otherwise indicated. We will quote mileage to you to the best of our ability but cannot be held accountable if mileage is wrong. You should use the manifolds from the car you are installing the replacement engine into. All engines sold are sold as "long block" units only and any additional parts received with engine (oil pan, exhaust manifold, water pump, distributor, starter, alternator, A/C compressor) are left on at our convenience. The warranty covers parts or exchange of the long block assembly only. The warranty does not cover labor or other incidental charges. The unit must be returned to OO Classic Cars before it can be considered for warranty. The warranty is void if the unit is overheated, run low on oil, or otherwise abused. All returned parts and cancelled orders are subject to a 25% handling and re-stocking fee plus the customer assumes all shipping costs and is responsible for shipping the parts back in order to receive a refund. Installation must be done by a certified mechanic.

If an engine is purchased for conversion, it is not guaranteed and will be sold "AS IS". An example is purchasing a turbo engine to replace a non turbo engine.
