Many thanks to all of you for the info.

I know this is an old issue, but I can't find anyone who makes them any more.  So, I guess my only alternative is to buy a used set. Please, I will very much appreciate is someone have any info about a set for sale. Thanks

My way of thinking.,,

1.- Those automotive engines are not design and will not stand 75% power output 100% of the time, as an aircraft engine do.

2.-  Rotary engines have many cooling, lubrication and fuel consumption problems to be considered as airworthy.

3.- An old aircraft engine as a 320 or 360 has more than enough power and reliability to be used on the LE. Also they can easily be updated with electronic ignition and /or electronic fuel injection (http://www.flyefii.com), performing much better that any automotive engine.  

4.- If you are planing to fly long legs, as I love to do, please thing about reliability first and performance second.

Be sure the tube flange is even and flat, also use a little Red Hi Temp silicon on the new gasket. That solved my intake leak problem. By the way, do not over torque the nuts.
