I picked up a new speed Demon annular booster 750 VS and replaced my 850 Holley DP. took it all apart and inspected it,no probs. installed and tuned I have way better idle,way more low end grunt and same top end. just thought I'd throw this out on the fourms incase anyone was considering a Demon carb but was turned off by the bad rep. I can't speak for any of the pre Holley Demon's though.
