[Fot] Spitfire Gearbox

[Brad Eells]

All of that certainly could have been done in this car, that was very competitive in its time.

I keep finding GT6 stuff in various places throughout the car. 

I have to keep both cars parts catalogs handy...

>>> Now that we've all worked out the oil cooler/filter issue, who wants to take a crack at Spitfire gearbox ideas?? I currently have a 1296 engine bolted up to a 1500 single rail gearbox. This year after the Kastner Cup, Marty Sukey suggested finding at GT6 gearbox as they have a closer ratio gear set - I think I even remember reading that some of the LeMans Spitfires had GT6 gearboxes. I'm having a difficult time finding one so I was going to ask the folks that have been this a lot longer than me, is it possible to just put GT6 gears (specifically 2nd and 3rd) into a 1500 Spit gearbox? Has anyone tried? Are there better options? I have two extra 1500 single rail boxes to mess with. Any help would be appreciated. Thanks!
