Kinsler Fuel Injection, Inc, 1834 THUNDERBIRD TROY, MICHIGAN 48084 U.S.A. www.Kinsler.com Phone (248) 362-1145 Fax (248) 362-1032 42 CROSSRAM MANIFOLDS CHAPARRAL BIG BLOCK CHEVROLET Designed for JimHall’s Chaparral 2J Can-Am car. Magnesiummanifold with 2.9” throttles; Lucas metering. About fifteen were made. The 2J car used a moveable Lexan skirt that ran 1/4” from the road all the way around the outside of the car. Two fans sucked the air out to make the car a rolling suction cup. SCCAbanned the car after one season as being beyond the technical and financial capability of other racers. Jim Kinsler was responsible for the manifold and suction fans in 1968-1969, while he was still in Research and Development at the Chevrolet Engineering Center, Warren, Michigan. GREENWOOD BIG BLOCK CHEVROLET FABRICATED Look closely.... this manifold was hand fabricated in 1977 at Kinsler’s from sheet and bar aluminum for Charlie Kemp’s Trans Am Mustang. A crossram was the only way to get the desired runner lengths while meeting the rule that the unit had to be completely under the hood. Used Lucas metering. A good flowing runner was developed, then exactly duplicated by forming four strips of aluminum over a pattern. Had 2 7/16” throttles. The top road racing teams now have manifolds made of carbon fiber. Kemp was quite successful. © 2017 SMALL BLOCK CHEVROLET Designed with small runners to give maximum low end torque for street use. Fits standard small port cylinder head. Throttle body mounting flanges are for Weber IDA 45 mm. Cast aluminum only. Four EFI IDA style throttle bodies with aluminum fuel rails and connector linkage Each Kinsler log has a 2 1/4” throttle at the front with cross- connecting linkage; Lucas mechanical metering This manifold was originally designed for John Greenwood, to fit completely under the hood of his Corvette. Available in magnesium or aluminum. Custom throttle sizes are available for good top end power combined with super low end characteristics. Phosphorous bronze throttle shaft bushings and spring screw universal throttle shaft linkage eliminates any possible throttle bind; works smooth! Available for EFI, Constant Flow, or Lucas metering. Note: Crossram units cost about twice as much as vertical types, as it takes a lot of extra work to develop a runner that flowswell, and the design and castings are also considerably more involved.
