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.
