I'd like to see a close up of that thermostat housing. It almost appears that you don't need that adapter plate if that is a by-pass housing. Did you see my pics? I may be biased, but it is the cleanest intake heating system I've seen so far. And it works well. It compliments the stainless fuel line and looks like it should have came that way from the factory. My motor(until next year
) is a 235, but I utilize the by-pass housing and pump from a 261 to heat my intake. This was recommended to me in this forum by 4onthefloor and it turned out better than I had imagined. However, both holes come out the PASSENGER side of the housing and I thought it would look even cleaner coming out the drivers side as it appears to in yours. That's why I would like to see a close up pic. My plumbing is 5/16" brake line with inverted flair fittings painted with chevyduty "stainless" manifold coating. You could probably use stainless tubing as well if you wanna spend bucks.
