DESIGNED FOR TRACKS WITHOUT 602 CRATE CARB RULES.
APPROXIMATE 2 WEEK LEAD TIME ON THESE CARBS
We think this is the best 602 Crate 4bbl Carb you can get - hands down! We've worked with our CarbMaster to design, blueprint, flow bench and race-prep this carb specifically for 602 Race Engines that run at tracks that have NO restrictions on Crate Carbs. Series Racing like in the Wissota region, IMCA Sport Mods, B-Mods and east coast Sportsman Tracks like Bridgeport.
This Holly 650 80541-1 style carb features:
* Blueprinting to max specifications* Redesigned fuel transition circuits, Metering Blocks and power valves to increase performance* Custom downleg boosters (DLBs) for added CFM* Glass window bowls to easily set the float level* Metal accelerator pump arm and idle thumb screw.* External secondary idle adjustment bracket
The KillerCrate SuperCarb will provide the most fuel, max CFM and fastest fuel atomization that you can pump into a crate engine to get the most performance without drowning the engine in fuel.
The magic that really makes makes this Carb Different than our Standard Race-Prepped Holly Carbs is the modification to the Holly down leg booster (DLB) so we can increase flow by 20-25 cfm more than the stock booster. The real advantage of the DLB is the positioning in the venturi. The bell of the longer DLB sits in the sweet spot. This increases the signal to the jet which atomizes the fuel better at a lower rpm. The engine will exit the corner harder with the longer DLB. Especially on starts and restarts. You'll see 10-14hp gain at the low end, better pull off the corner. Better off the corner means you'll have more top end at the end of the straight away. Glass Float Bowls makes it easier to set float levels.
THIS IS NOT LEGAL for DIRTcar applications and will not pass go-no-go gauges; but is legal at certain tracks like Bridgeport and the Wissota Series. Please consult your rule book if you request this modification. PM us if you are interested in sending us one of your carb Cores that we can remanufacture into a KillerCrate Holly Super Carb.
Shipping and Insurance Included.

NOTE FOR TRACKS THAT DO NOT HAVE CARB CFM RESTRICTIONS : There are tracks which allow 4-bbl Carbs without size restrictions and even allow up to 750s. In our experience - A 750 is too big for a 602 Crate.
Crate racing was intended to level the playing field. However, after several Track Championships and winning 7 out of 14 Races at Devils Bowl in 2016, we can tell you that Not all 602 circle track Crate Engines for Pro Stock, Thundertrucks, Sportsman Modifieds and other types of crate racing are created equal. If you want to run up front - there are a few secrets that you need to know.
With the proper break-in technique and a little magic - your motor WILL create MORE LEGAL horsepower and last longer. The correct distributor phasing, timing marks, race-prepped carburetor, carb spacer and better Valve Springs can significantly improve performance.
