3883948 - 1966-68 396 325 L-35                   427 385, 390 L-36   That's all my book says.   If I remember correctly, the 390 hp Vette engines were oval port (my friend had a '68 390 horse 427 Vette in high school and he always bitched about having oval port heads).   The only way to know for sure is to check the casting number on the heads.   cYa-   Herb Lumpp 1966 El Camino ACES #3509 http://web.tampabay.rr.com/herbsworld/index.htm     ----- Original Message ----- From: Lojac To: [EMAIL PROTECTED] Sent: Thursday, February 21, 2002 8:37 PM Subject: Re: [Chevelle-List] Port Shape?? By intake numbers are as follows:  Casting # GM 1 T 3883948 As far as the information that I can get online, the intake is oval port.  Is that whay you come up with?

If you've seen both oval port and rectangular port heads with the intake in place before, they're very easy to tell which is which, other wise it may be difficult.  Maybe you could get the casting number off the heads (it's under the valve cover) or the intake casting number so I can check my book.   As for the block, my book says: "1967 396 325, 350, 375, 2&4 bolt"   cYa-   Herb Lumpp 1966 El Camino ACES #3509 http://web.tampabay.rr.com/herbsworld/index.htm     ----- Original Message ----- From: Lojac To: [EMAIL PROTECTED] Sent: Thursday, February 21, 2002 7:47 PM Subject: [Chevelle-List] Port Shape??
