Thanks. It will be a summer ride only, so no concern about very cold temps. The engine should put out 400 ft lb of torque with a nice flat torque curve. Looking forward to getting it on the road this summer.

Do I still need to run a hose from the intake manifold to the water pump? I may not put a heater in it for the first year.

Thanks.
