Re: stock BB manifolds?
Bolt patterns are identical, but head port size and shape may differ.
If I am not mistaken, 396 has D or oval ports, and the 454 has rectangular ports. Aftermaket haeds usually have rectangular ports that are larger. What type of heads do you have? Last edited by suprachrgd82; 12-09-2009 at 04:31 PM. |

Re: stock BB manifolds?
Im thinking it has stock heads since the previous owner said he was running manifolds before he pulled the motor to paint the engine bay?

Re: stock BB manifolds?
Any more info on the motor/heads? Cart or truck motor? Year of production? Any casting numbers?
Truthfully, it would be pretty easy to pull the manifold and have a peek. Even pull the carb, if you can see down the plenums. Post a pic, if possible, of the current heads and manifold. |

Re: stock BB manifolds?
they would fit, but you might ebay the Chevelle ones and pick you up a set of whatever you want with the money. Chevelle correct dated stuff brings good money. Trevor

Re: stock BB manifolds?
They will bolt up but the collector will point the wrong direction and you won't be able to hook pipes up to it. I have 2 sets of big block manifolds if you're interested in a set PM me
 You know me from PT.net so you know I'm trustworthY  aka hirdlej
