Thanks guys.
With all your comments I might just run my single 32/36 downdraught weber on the A15, as I have priced a twin carb manifold from redline performance and they are $265inc, then add another $20.00 each for soft mounts and a linkage kit will set me back about $95.00
I also have to find ram tubes and it's highly likely they will need new chokes, and lastly I will have to get someone to tune them correctly.

All I can see is $$$$$$$$$$$$$$$$$$$$$$$$ signs in front of me.

But please keep the comments coming.
