Yes. You're the one who clued me in about them. I made arrangements with him so I could buy/test with them just before the engine problems. The props that I was running were loaners and not for sale. I've got to see where I'm at with the new engines now prop wise

I can't afford to replace parts that aren't broken so I'm going to reuse the 305 heads and current intake. We're going to bump the comp about .5, run a few hundred rpm higher and go more aggressive with the cam to take advantage of the exhaust I have now. I'll try some 4500s with an adapter to my intake also

did you ever mention how much water pressure you have?

bck

Water press is generally never below 20 when on plane. Measurement taken from intake below t stat housing

240* oil temp is not too hot and should not be an issue.

Wobble

Really should run the oil filter after the cooler. Coolers often have little beads of solder rolling around in them, next stop is the mains.

If you are talking about where to measure temp then that is another discussion

bck

I'll verify how the filters are plumbed in relation to the cooler tomorrow. If the temp sender is after the cooler and read 240 how hot would the oil likely have been before the cooler?

Wobble

That depends on the size of the cooler and the water temp, my multipass Teague offshore cooler supposedly can make a 50* drop in temp.

Oil is cooled through 1 side of a merc bellhousing cooler

bck

Found a picture on the phone. Wouldn't you need to know how the fluid flows in side of the filter housing to determine if the sender's are before or after cooling? And how does that flow change as the t-stat opens and closes?
