[Fot] Weber DGV Jet recommendations - 1500 spitfire

[fpspitfire at insightbb.com]

I'm fully aware that this situation isn't great and I'm fully aware of the benefits of dual and single sidedraught carbs.  While it's great to say just put a sidedraught weber on...I have to work within the rule structure of the SCCA Limited Prep engine rules..

Currently that rule is:
1.5" Unmodified Stromberg or a 32/36DGV on an adaptor.  What we are currently finding on the dyno is that the 32/36 is an improvement over the Stromberg, it just needs to be tuned more and I really don't want to buy 50 jets/air correctors to tune it.
