Hi Boxhead,
The 16's are a good compromise. Wilf has 16's on his Cobra and it looks fantastic. There are a lot more performance tyres available in 16 than 15 but I'm not sure if you can get them as wide.
Check out Wif's fine looking Cobra here:

Phil,
why did you change the front pulley/ balancer? was it increase clearance over the steering rack or just for the under drive? From memory you were setting up an electric water pump on your LS1.
Where are you getting your aluminium flywheel and HD clutch from? I've been thinking more about running an aluminium flywheel lately. What sort of $$ for that setup?
Wilf,
I probably need to do another progress picture of me sitting in the car with some underpants on my head.
Craig,
The goodies may be hidden but I know they are there. I get just as much enjoyment out of making them anyway.
Cheers
