Holley 4777 DP
Hey, quick question for you guys: how high maintenance is the Holley 4777? I've heard it both ways, but I was recently told by my mechanic that I can look forward to tuning it every week, that its an extremely high maintenance carb. How true is that?

Nope, no racing. Just cutting up around town Well, that doesn't sound too bad. It seems to be dialed in pretty dang good right now. Though I was told the metering block would need to be adjusted regularly.

Holleys really depend on the condition they are in. If its an older carb, yea it will probably be a pain in the ***. Mine however just had a rebuild bout a year ago, let the car sit for bout 5 months, cranked it up no prob.

I have used a 780 VS and 750 DP, both cleaned and rebuilt before I used them, and both were mostly maintenance free once I got the setup right.
