Beginner Road Track Racing: Feedback on Engine Options Wanted

@replicaracer43 nailed it. WIDE powerband is where you want to be. stock magnum internals are up to the job, just meticulous attention to detail and prep. i'd talk to ken up at oregon cams and have him regrind your stock cam to spec for the application.

a magnum (or LA) can make some very respectable power without breaking the bank and live to tell the tale. i personally would build a bomb proof bottom end and spend a grip of dough doing it knowing that i could upgrade the top end later on down the line if i wanted to hunt for more power. some of the components you select can be worth 15~20 hp at a clip and that starts to add up on the bottom line. the added bonus is that some of them may be lighter than factory components as well, which can equate to a more responsive motor.

100% spend your money in the chassis and brakes. a car with good well sorted out suspension will absolutely far surpass something with 100+ horsepower. the whole: more fun to ride a slow bike fast than a fast bike slow school of thought.
