You can run a four valve, four cylinder in H/EA-we have one in my car-Al Ackerman built it using a block and head out of the Colorado pick-up-it is a 2.9 liter motor (177 cubic inches) in stock form-we race it at 170 cubic inches. For H/EA, the motor must use carbs and the weight break is 8.25 lb.cubic inch. Fuel injection can be used in L/A or L/AA and the weight break is 10 lb/cubic inch (2 valve) or 10.5 lb/cubic inch (4 valve)..
