Edelbrock's new Victor two-piece intake manifolds are designed for racing small-block Chevrolet engines utilizing conventional port cylinder heads, including All Pro 11-degree and 13-degree, Dart 12.5-degree/15-degree/16-degree/18-degree, and Brodix 13-degree/13.5-degree/15-degree/16-degree/ 18-degree series heads.
"These manifolds can be machined by professional porters and engine builders to fit multiple cylinder head bore spacing and block deck height combinations and will save the racer a lot of money in the process," stated Edelbrock Engineer, Rod Sokoloski. Sokoloski and the engineering team achieved the savings through a unique two-piece design that allows porting work to be done in both the plenum and runners, quickly and accurately, without having to saw the intake in two and then weld it back together.
The two halves are securely sealed by a 3/32-inch nitrile O-ring seal and fastened together with 5/16-inch shoulder fasteners. You can see the channel in the bottom righthand photo.
Multiple options are available and include a standard and plus-0.550-inch flange to accommodate most deck heights. There are two internal metal thicknesses to provide plenty of material for the porting process. The standard internal metal thickness version is ideal for hand porting and the "CNC" version includes (plus-0.100-inch) of material added to the plenum and runners, making it ideal for custom CNC porting and 4.5-inch bore space heads, like Brodix's new 13-degree head. Valley plates are also available with standard and plus-0.550-inch flange thickness to accommodate 4.4- and 4.5-inch bore spacing and 9.025- and 9.325-inch deck height blocks. Additional applications are coming soon for symmetrical port race heads, including SB2 (4.4 bore space), ROX (4.5 bore space), Brodix BD series (spread port), and Dart 9-degree cylinder heads.
