Might get it cleaned out... And reamed for the pleasure lol.
Nah no stock engine fan, no room with the l and rad. I got a datsun 1000 metal fan to fit but the metal blades need to be cut down as the tips clip the bottom tank just.
That will affect the fans effectiveness too.
I need to trim the rad support more to clear more air flow through rad. Thought about sealing the edges but shrouding a push fan is pretty impossible.

Planning on fitting the reversed scoop bonnet once I Paint it too, that may assist a little to suck air out of the bay
