Sport 40 Engine

[AzMandella]

Ok so NAMBA rules say for Sport 40 engine rules are 5.74 to 6.56 cc (.35 to .40 cubic inch), front intake, side exhaust, no full wave tuned pipes. Is K & B the only engine available for this . I dont see any other front intake with side exhaust by any other manufacturer .

Try Sport 40 2

Try Sport 40 2

Mike is correct, you are looking at the rules for sport 40-1 (class hasn't been run in years.)
Look at the for sport 40-2

NAMBA most run Sport 20 (.21 engine )and Sport 40-2 (.45 engine) also can entry classes to A hydro and B hydro Another not popular for sport 40 (.35 to .40 engine)

So will a Novarossi .46 meet the rules ? Or go with a CMB .45 ?
