I think the only place to tap into the pressurized oil system for a external oil cooler is the external pipe that runs up to the cylinder head.Unless I'm wrong, using a thermostat in the external oil cooler could lead to a catastrophic failure of the rocker arms, the valve guides and the cam followers.If the thermostat decides the oil is too cool and it doesn't need the cooler it will prevent the oil from circulating up to these parts.The only way it could work without causing this problem is if the thermostat allows a free flow past the cooler when the oil is cool and it diverts the oil thru the radiator core when the oil is hot.
Tom, since you're here and we're on the topic...do you think the spin-on filter mod is a good idea or does the traditional filter work well enough? I got my filter and mounted it in the airstream to try and get a bit of a radiator effect on my 350, but I'm wondering if it's worth it to try and plumb it back into the Fireball when I get it all built.If I do add it to the Fireball, I'm going to mount it closer to the engine and more out of the general air stream.

The extra volume of oil doesn't hurt either.Mine is mounted to the engine mounting plate.Chuck.
On pavement only, not too big of a deal, but I inevitably do stupid things for amusement.
I've never done anything stupid on a motorcycle..... Except those times I took my YZ 125 race bike to the liquor store for beer, with the front tire in the air. ACE - Will this external filter adapter work on my '58 Trailblazer? I plan on doing a lot of daily riding and mountain trips. Also, I will be running Excelerated performance oil and would like to be able to run a synthetic fiber filter to get the best out of the oil. Where are these filter kits available?Scottie
B.W. - That looks very clean and something I'd be interested in doing. Where did you source your parts from? Where did you tap the oil lines into? Were there already holes there? Scottie
Thanks Bullet Whisperer!ACE - Do you know if it's possible to tap into my 700cc case/cover to install the external filter in the same fashion that B.W. did?Scottie
