396 cast iron intake manifold specs
I have searched high and low on this site for the answer and I am sure its out there somewhere. So if this question is a repeat, my apologizes.
Does anyone know the specs for the stock cast iron manifold (back and front height)? Stock 67' 396/325 with Oval ports. I would like to compare to new options.
In one of my other posts I talked about a hood clearance issue after installing a street demon (#1904) on top of the stock cast iron spread-bore intake. I had to use a 3/4 spread-square bore adapter which added 3/4" to the overall height. The street demon is about 1/2" taller than my old q-jet. So over all I added 1" to the total package. I had to go to a 2" vice 3" air filter for clearance. Don't beat me up about abandoning the q-jet. I am very pleased with the street demon.
Now I am looking for an new manifold (Mama said I could get one for Christmas). I am looking for a stock replacement which allow me to remove the adapter and give me enough hood clearance. Here are my planning factors: idle -6000 ish rpm range. Stock 67' 396/325 with Oval ports. Not a racer, just for cruising.
I have looked at Weiand 8122/23 and Edelbrock 2161. I think either one will work, but I am open to suggestion and recommendation. Just need to order before Mama changes her mind. I need one of two things. The Height specs for the stock cast iron manifold or someone's solid recommendation and experience with another manifold. Thanks in advance.
