very cool. I infact have the same setup. However i'm still working on going over the engine and getting it back together before running it. Right now the head is off and new head stud and gasket etc.. is being done first. All the maintenance then the go fast stuff. But, it's all here waiting to go on. I have one 14" slim fan as it is now just sitting aound. Perhaps it might work. Of could it be solved by trimming off some of the shroud? Well I'll wait for the pics. Thanks

I'd be interested in seeing those pictures you have of the 20g setup and what little things had to be done to make it work. Thanks, Jason
