Hey guys. I’m new here. Recently purchased a 1969 cavalier ski boat with a q in it. I’m going to build a new engine and wanted to put a standard edelbrock rpm air gap intake on it. Well.. I’ve studied the diagrams closely and it looks like it may work. BUT! On the standard seawater cooled q’s, with the original intake, the flow of water goes from the seawater pump, circulation pump, to the manifolds, the block, the heads, the intake then back to the seawater pump IF the thermostat is closed. Can anyone confirm this?
The dilemma here is with an aftermarket intake like the rpm air gap, AND the suggested 327f thermostat housing and spacer, that while the thermostat is closed, where is the water going? I don’t think it’s going where it’s supposed to be going because with the thermostat being closed, wouldn’t that block the flow to back to the circulation pump? I’m a little lost here. I would think you’d want a cold engine to warm up by circulating the water through the block first, then opening up the thermostat and then going out the manifolds via the two hoses that go from the thermostat housing into the manifolds. I need an answer here, this has been bugging me and I just found out how to create an account. If this is in the wrong spot, please move it! Thanks, much appreciated.
