The cooling water is supplied by the jet pump, and it was open cooled. As such, I had to adjust some of the tables in the PCM so that it knew that ~150-160*F was "warmed up", or else the fueling and timing would have been off since there are ECT modifers.

and upgraded the springs in the valve train ,the camshaft I don't know but it makes some reversion so maked the exhaust dry ,the ecm and harness (not the easiest one to program) I got from mast motorsport when we started there was not much out to convert the ls to marine I bought a closed cooling set from the pcm zr1 and a pair headers from cmi who first send the wrong ones(normal sbc) to europe ! luckily i could sell them here and bought a set ls ones where we dynoed the engine whit ,later I bought the lighting wich have a much nicer collector so might find another few hp !
The tailpipes we made in-house whit o2 fittings in them ,now I know why headers are that expensive !!
we put the headers forward due to the space behind the engine and the engine makes more power whit some length in the exhaust .

How is this for a crate LS motor. Cost is very affordable. Interesting to have a bill of materials needed to marinize this beauty.
