SUPPLIERSMaximum Torque Specialties (MTS)http://www.500cid.com/ Marty is the tech guy and who'll be doing the engine build - I met him (online) via one of the Cadillac forums.
He came up with a spec based on my original ramblings and it's grown from there. I think he was a little reluctant at first (my intake idea does directly conflict with the rest of the motor) but as we've got into it more seemed to realise where I'm coming from . . . Hopefully !

USAHells Gate Hot Rodshttp://www.hellsgatehotrods.com/I originally spoke to Andy via eBay but later the deal was struck through Stromberg as they - by coincidence - knew him and got me an even better deal.
My limited dealings with Andy have been good . . he's been helpful in getting the custom kit together and wasn't phased when asked to ship to the U.K (not something he normally offers).

USAStromberg Carburetorhttp://www.stromberg-97.com/index.htmlI initially contacted Stromberg (who're based in the U.K !!) about some cool mugs that I was after . . . Clive, there, helped me ship 6 over from California and got me a good price on them. I then had some T-shirts off of him, too.
Momentum was building on the Cadillac-front so I contacted him regarding my stupid intake manifold idea . . . He was helpful and genuinely interested.
Without going into details on open forum, he's offered me a cracking deal on parts and labour and is taking my old 365ci motor as part payment.
I don't build Hot Rod's everyday but If I did they'd have nothing but '97's on them as these are the kind of guys you want to deal with !
