Re: [Chevelle-List] Port Shape??

Yes, the intake port is the same shape as the head port, you can't install an oval port intake on rectangular port heads for example.   The block doesn't care what port shape the heads and intake are.   Typically, oval ports are for more low rpm torque and rectangular ports are for high rpm power.  Stock oval ports flow less cfm and have smaller valves than rectangular ports.     cYa-   Herb   ----- Original Message ----- From: Lojac To: [EMAIL PROTECTED] Sent: Thursday, February 21, 2002 8:47 PM Subject: Re: [Chevelle-List] Port Shape?? Intake port shape=head port shape??  Does this have anything to do with the block or can you change the heads and intake to a different shape?  What are the pros and cons of the different shapes?   Lojac
