hey guys i was doing some research and stumbled up this little mod
what you do is take your cam and have a new one ground opposite
so that the intake comes in through the exhaust and vice versa
its supposed to add about 20 hp on a pushrod 660
cause of the change in wave dynamics
only thing you have to worry about is venting the exhaust out from under the hood and refitting your fuel injector into the exhaust manifold
also since the intake comes in through the muffler it makes ram air alot easier
if anyone tries this let me know how it goes
