Demon Street 625 Carb on 440 RC?
I have an '86 RC with low compression 440/auto/3.55 gears/33's that has dual plane Edelbrock intake, Lunati Voodoo cam with 213/220 duration, .454/.475 lift, 108 CL, headers...
I've always had a hard time getting the carb right, the carb on it now is an Edelbrock Thunder Series 650, not running that great...so was looking at this Street Demon carb that looks like a hi-tech TQ. It's a street driven truck so throttle response and low RPM power is desired.
Would this carb be enough?
Any advice, experience will be accepted. Thanks.

I will try that carb out. Will bag the rebuilt carb and go new. And the timing I'll check out...stock is around 12 btdc right? Hopefully I'll get some compression back with heads I'm having rebuilt.

Thanks. Well, when the new carb was installed earlier this year, the fuel pump was also replaced. This choking/no down-shifting happened last month as well. When it first happened, I got it warm, gave it a good shot of carb cleaner, drove it, and the trans downshifted properly. But after about two weeks, it's back to choking and not downshifting when I punch it. If it's relevant at all, the idle was just adjusted and return spring was replaced... but the issue was identical before those two changes. Thoughts?

Thanks. The carb will kick down after start-up in P or N, it's just when I punch it when driving... it will not drop to 2nd gear, etc.
