Hi krazy kanuk,
This sounds like a wonderful project. I just wanted to let you know that if you are going for real scale then you will have to shorten the cowl if you want to do a Vokes filter as the MkIX (as in the CARF kit) had a longer cowl than the MkV that actually made use of the filter. If it is going to be sports scale it will be just fine and be an effective way of cooling that in line engine.
I'm subscribed either way.

Cheers,

Brad
