Holley Truck Avenger Offroad Carburetor 670 CFM for Up to 400 Horse Power References part numbers: 090670 The award-winning Holley Truck Avenger carburetor is the first carburetor designed from the “flange-up” as an off-road carburetor. No other carburetor comes close to the Truck Avenger's ability to offer peak performance at extreme vehicle attitudes over rough terrain, and lightning-quick stump-pulling low speed response for towing and mud-bogging. Exclusive dichromate finish is built for durability and good looks without the maintenance of a polished carb. Designed for the off-road enthusiast but works equally well in street truck applications. Packaged in attractive New Truck Avenger box to complement existing Street Avenger styled packaging for easy plan-o-gram layout.

Customer Rating: Summary: 670 CFM on my AMC 401 Comment: Replaced my factory Motorcraft from my AMC 401 that was in my 72' CJ5 and replaced it with the Truck Avenger 670 CMF. It was not to bad to install after I got all my parts. No cable bolts so I was back and forth from the parts store. Was not really a bolt on need a couple more spacers to raise the carb up. Runs great and has great throttle response. Really worth the money. Customer Rating: Summary: Holley Truck Avenger Comment: Do not expect to the Holley Truck Avenger to be a "bolt on and go" carb. It has a serious flat spot just off of idle. Seems to be a very common problem with this carb, especially on vehicles with a cam or engine that is not stock. However, If you are able to "tune" the carb so that the off idle flat spot goes away it will be the greatest off road carb you could ever find.
