Combo 35.
Combos 35-38 use GM heads that have $1250 worth of work done. These heads have 1.94/1.50 in. valves like the Torquers. These heads have the basic work done, such as a 3-angle valve job and minor porting.
Combo 35 uses the 600 cfm carb, Performer intake, and 262° cam. The result is 309 HP and 358 ft-lbs of torque.
While the Torquers were not tested with these components, the re-worked GM heads made 45 less HP and 26 less ft-lbs of torque than the Sportsman II's with the same setup. |
