Edelbrock 1910 carb help needed

[Bgdaddy455]

Hello all, I'm about to rebuild a Edelbrock 1910 carb which I have never done before but I have rebuilt a couple Holley carbs with no issues so I'm just a little green lol. I have an olds big block pushing just north of 500 HP with a Holley 770 CFM square bore to spread bore intake and I was told I'm losing power with that setup. I do have the adapter plate but apparently it doesn't solve the HP loss. I do have a 1910 850 CFM carb and from what I'm being told it will work much better than the Holley as it will match the spread bore intake and is 850 CFM. Is there someone who could give me the specs on what the carb should have to support 550 HP?

The 1910 is a factory high performance carburetor.  It still needs help in a few areas.  The accl pump in them is crap and so are the ones in the kits they sell for them.  I sell custom rebuild kits for those with a much better accl pump, .149" HP N/S assembly and everything required to get the carb up to par.  It may need a slight recalibration based on the engine specs but I don't know all the details.  IF you want the best kit currently available for that carb contact me at the shop, 740-397-2921.....tks...Cliff
