Thanks for the kind words, guys.
Andy - Rides will be given to those who have medical clearance, sign a liability waiver, and have a note from their significant other. Engine weight is about 75lbs lighter than the Healey lump.
Sparkie93 - Hope the Tiger manifolds work, but I'll keep the Falcon ones in mind.
Healey 100 - Guy named Mark Lambert did a 280ZX drivetrain swap about 15 years ago. Motor fit like it was made for the car, motor mounts were even in the same place. Fuel injection and AC. Very nice!
Dougie - Unless your name's Norm Cowdrey, I ain't buying that!
Legal Bill - Never drove an S2000, but understand you really need to rev the heck out of them. Honda makes nice motors, so could be a winner.
BabaKahawa - I'm fond of the stock body with a big motor "Walk softly, but carry a big stick."
Hedgehog - Swapping a six into a 100 will take a lot of work, I'd probably do the Bimmer swap into a six-cylinder car. Might as well get the motor from an M Roadster while you're at it.
