Hey guys. It's time to start looking for a decent carb for the Cuda. Specs are below, but the car will see 95% street use. So looking for a street friendly carb, possibly even with a choke. Car runs too fast with no roll bar as it is, so max power isn't as important as street manners and easy tuning. If it's running 11.20s with a crappy tune and I can only run 11.50s max, I can stand to lose some power when it's tuned correctly. The current carb is what started life as a Holley 750, and was heavily modded by a local carb guy and supposedly will flow 910. Makes great power, but it seems to always run rich. Smaller jets seem to be no help. So a fresh street friendly carb seems like the ticket. Demon Carbs look tempting, but I've never messed with one. Thanks for your input.

69 Cuda. 3600 lbs with driver.

418 stroker 10.3:1 comp

Fully CNC'd Eddy Heads from Hughes.

Ported Airgap intake.

248/252 .600/.610 solid cam

Holley 750 modded to flow 910 CFM

MSD E-Curve dist with 6-AL

TTI torque stepped headers w/ Ultra Flo mufflers

3:91 727 Tight 10" converter.

My Edelbrock headed 408 went 10.06@130mph last year with a 750 holly so they are not a bad carb. Would it have gone faster with a bigger carb, I will find out this year.

More info on the carb is necessary...

I am assuming it is a double pumper. Are you running power valves? What is you vacuum at idle/cruising?

There was just a decent thread on power valve tuning a few days ago...

I had a 750 on my daily driver, no choke, and that thing was spot on driving around...

The carb you have should be fine.If you don't want to tune it yourself send it to a carb guru and have the fuel curve checked/set.A change in the air bleeds may be all it needs.

The Demond carbs I've worked on had issues of not
responding to the idle mixture... I have a 850 holley
DP on my 416 and it loves it. quick response and
makes just under 600hp on the dyno... I think you
would be better off with what you have.. it'll need
some minor work to lean it out... if you dont like
playing with them or dont know how, take it to a chassis
dyno

Thanks to all who chimed in. I know this is a little late, but I figured I would update those who were interested. I went with a Holley 770 Ultra Street Avenger. The difference in drivability is night and day. Love having a choke. With the heaviest secondary spring in it on a muggy night, it went 11.60s at 115 with about 3/4 throttle. Were there better carb out there? Maybe. But I'm extremely happy with my purchase. Dialed in with light spring and properly tuned, and full throttle, I'm not convinced it will be any slower than it was with the old "race" carb. But because of the carb, I've put more miles on the car in the past month than I have in the past 3 years. Street tires went on a couple of weeks ago, so I'm done racing for a while. Between tires and carb, this car is an absolute dream to drive. Thanks again to everyone who chimed in with advice as this car has evolved into what I have wanted over the past few years!

Funny this came up today. i just switched my Duster over to an 850 alcohol carb and was going to go to our local tracks test n tune but I never finished it up till 2pm so if the rain holds off I may hit tomorrows race at PRP to see what she does.

I changed directions... pulled the 850dp off and just
finishing up installing fuel injection.. trying to
move into this century.. should make more power and
it'll think for itself.. this is on my street/strip Rampage

I considered a Terminator setup. But for what I do with the car, I don't know how much happier I would be spending the extra $1500 on EFI vs installing my Dana that's been waiting for 3 years now, and upgrading my 727 to be less likely to explode. Glad to hear EFI worked well for you.
