Summit's new Street & Strip carburetor looks similar to other aftermarket performance carburetors; in fact, it closely resembles the Holley 4110 carburetor of the 1990s, a two-piece design that was a solid attempt at building a better street performance carburetor. Yet, Summit took a different approach by remedying many of the pesky carburetor issues we frequently complain about.
The Summit Street & Strip four-barrel is a performance enthusiast's carburetor. Available in 600-675-cfm configurations for approximately $250 and as 700-795-cfm versions for just a few bucks more (under $350, depending on how the carburetor is configured), the Summit Street & Strip is a great value with these features:
The Summit Street & Strip...
The Summit Street & Strip 600-cfm carburetor is an easy bolt-on for vintage small-block Ford engines. If you have a 351, it's suggested you go with 650-675 cfm for improved low- to mid-range torque. For FE big-blocks, step up to 700-750 cfm. Cobra Jets need 750-795 cfm.
- Solid aluminum casting-warp resistant for outstanding calibration.
- One-piece design eliminates traditional fuel leaks.
- 30cc accelerator pump; dual 30cc pumps for mechanical secondary versions.
- Interchangeable discharge nozzles and idle circuit restriction.
- Color-coded vacuum ports for easy installation.
- Extra thick base and gasket for better sealing.
- Externally adjustable center-pivot floats with clear sight-glass fuel bowls.
- High-flow power valve channel. Mechanical secondary carbs get two power valves.
- Easy electric choke adjustment.
- Each is wet-flow tested and ready-to-run right out of the box.
What's really cool about this carburetor is its use of Holley parts; it accepts virtually all Holley 4150/4160/1850 components. This means you can service the Summit Street & Strip carburetors with Holley power valves, accelerator pump diaphragms and cams, floats and float needle valves, main metering jets, choke assemblies, vacuum secondary springs and diaphragms, accelerator pump discharge nozzles, and linkage adaptors.
What we appreciate most about the Summit Street & Strip is its sweet compromise between the reliable Autolite 4100 and the traditional Holley 4150/4160/1850 carburetors.
The Street & Strip carbs use...
The Street & Strip carbs use an adjustable electric choke. You can wire it so it comes on when the ignition is switched on or you can go with a manual choke and dial in cold-start performance yourself.
Summit's Street & Strip carburetor...
Summit's Street & Strip carburetor presents some of the same challenges as a Holley when it comes to interaction with a classic Mustang. For example, throttle linkage is the same as a Holley, although Summit makes it easier with a throttle rod adaptor. If you don't use the Summit adaptor, use the small hole next to the large hole, then drill a small hole in the rod end and use a cotter pin for security just like you would with a Holley 4150/4160. All of the pieces are there for '69-'73 throttle cable.
The square-bore design is...
The square-bore design is compatible with just about any Ford four-barrel intake except the '71 spread-bore (Rochester Quadra-Jet) on the 429 (non-Cobra Jet).
