Edelbrock Carb Install
1 Attachment(s)
Finally replaced my original 15 year old Weber carb.
Installed a new Edelbrock 600 CFM Marine 1409 carb. Experienced all around better performance although top speed was equal to the old Weber. Just to note that the Weber is the identical physical design to the Edelbrock which was a original Carter design. Ran well right out of the box except for a little adjustment of the idle mixture screws. All the linkage, fuel line, choke, brackets and fuel pump overflow tube were simple bolt ups. My old Weber needed a rebuild so just decided to replace due to some rough running and primary to secondary transition issues. Was going to install a 600 Holley but just wanted to make it easy without having to mess with throttle bracket mods. Thanks |
Re: Edelbrock Carb Install
Nice, I almost swaped out my weber/carter carb for the edelbrock but was hesitant if I would notice any gains. What intake is that? Is it a edelbrock RPM? That was intake I was looking to mate to the edelbrock carb, but with the restricted heads on my stock 350, didnt think it would benefit from the increase in air/fuel flow. Looks nice in that engine carpartment though.

My intake is the Edelbrock RPM Air Gap. I replaced mine rather than rebuild it and like i mentioned all connections were the same. Thanks |

Good looking engine compartment. Good post.

Re: Edelbrock Carb Install
I am rebuilding my Quadrajet. The Marina wanted $500 plus. I have it torn apart and cleaned. Just waiting for the carb kit. I'm looking at under $100. I hope it runs o.k. or I will have to have someone do it next spring anyway. Just trying to save a few bucks.
Next boat is fuel injection for sure. Nice installation in the pictures. Danny |

Hey Mariah 350,
The marina wanted 4 x $91 labor = $364 plus parts. Maybe it would have come in under $500, but still expensive none the less. I think your boat kicks butt. Is that engine stroked? 64 mph, how many horsepower are you putting out and what kind of exhaust manifolds do you have on there? Give me the list unless it's a secret. I have a stock 5.0 LX (95 Z202). I can get 45 mph (GPS) with the family, gear, gas. I'm running a high-five 21p prop for tubing and skiing. I wonder what I could run with a 3 blade. I bought the boat with a 4 blade so I've never had a 3 blade on it. I'd love to put thru-hull exhaust on it. I had a mechanic quote $2000 (1500 parts 500 labor). I don't think the kids would appreciate having to take sports off for a year though. Danny |

Re: Edelbrock Carb Install
Hey 350, you appear to know what you're doing. I was just looking at Edelbrocks to replace my tired old Weber on my '95 Talari. If was originally a 7.4L, but a few years ago I put an 8.2L GM crate motor in it. Two questions, is this a bolt on replacement (appears so), and I was thinking about going to a 750cfm model to let those cubes breath. It hits the rev limiter around 4800 and I figure thats all the farther I want to wind that monster. What are your thoughts on the size?
Thanks Doug |

The Weber 4 Barrel is identical to the Carter/Edelbrock. The two models in marine config are the Edelbrock 1409 600cfm and the 1410 750cfm. The 1410 750cfm would be fine for the 502. Like I said in previous posts, the Edelbrock will be a direct replacement for the Weber. Edelbrock does make a calibration kit with mulitiple sets of metering rods with additional primary and secondary jets. There is even a primary metering calibration chart to fine tune beyond out of the box setup which is very close as it is. I enclosed the users manual to read which has good information on the Performer Series. The Edelbrocks are very close right out of the box but if you need to there is info and support. The Edelbrock Marine is generally calibrated on the rich side due to a constant load condition on a boat. Good Luck |
