Bobby;
If you get a chance, take a trip down to London Ohio for the London cobra show June 17-22. You will find almost every make/engine/color/transmission combination you could imagine done there by someone. The people that put it on are wonderful.
Take a look at their web site:
London Cobra Show - The Ohio Cobra Club
Good luck with your decision -- everyone here knows how difficult all of this can be.
