Scott, if you decide to sell that Greddy oil pan, let me know.
It would dress up the engine we have on a test stand for show and
tell. Milo
Maybe Scott will loan it to you Milo. Does not look deep enough
for aircraft work but most observers don't need to know that :)
BTW Are you getting that engine ready for Sun N Fun Milo?
If so are you sure it will be ready? Ernie might have to drive
up to Bell and build a fire under Tracy to get his test engine
started and loaded onto a trailer pretty soon. If Ernie can't
make it I'll be driving this year so I can pick up Tracy's test
stand. I can do that a day or so early so I can help Tracy get
it cleaned up and maybe paint the stand. We hope to have at least
one engine running in the work shop tent this year.
Dave Garber's turbo charged Huff and Puff was a big hit in 2002 :)

I'm definitely putting the pan on my RX-8, because it allows about
another quart of oil in the sump. I might could be talked into
loaning it out for a good SnF demonstration.
Scott Gettings
Another quart is a really good idea. If it is not too
much money I might get one for my RX8. Can you get it on there
without taking the engine out?
