While were on this subject. I picked one up from summit, now I need to know the oil flow direction for a 502 Mag MPI??? After looking at the directions on the oil Stat, Theres a diagram on how to plumb it in line. Are there arrows on the remote filter housing showing the flow direction???
Thanks

yes, there are on my 454.

Heres how I plumbed mine. The hose on the far right is oil going out from the block adaptor to the filter. The return from the filter loops down to the bottom right on the thermostat. I used a pipe nipple to connect the thermostat to the return port on the block adaptor.

I'm running a mocal unit which fits under the filter like a sandwich adapter. Only wish it had a litlle higher opening temp. It is around 180. Same size as a sandwich adapter, and has larger ports and passageways. Got it from racerpartswholesale.com

The one on the lower left..

That looks like an even cleaner install than the permacool. Ill try it on engine #2.

It's exactly what I was looking for. I can't remeber what oso'r told me about it..

One thing to watch for. I think it is only made to fit a gen 4 block. I have it mounted to a gen 6 and had to take a little material off of the center part so that it would tighten before bottoming out. No big deal.

1500,

What's a "cruiser type" boat? What is the line between the flow capabilities of a Perma Cool and a more macho KE type unit?

What would be wrong with 2, count 'em, 2 PCools in parallel for $70 instead of the gaddawful $450 KE mother...

They have an inline oil thermostat that looks familiar with a choice of 190 or 215* thermostats. They have a lot of other neat stuff ment for cars racers that will work great on a boat. They are trying to lear to speak "boat", but they are very polite and helpful. They also are much CHEAPER.

I wanna say that the mocal was around ~$80. Has 1/2npt ports, but uses a PF-24 filter.
