Intake manifold measurement?

[mcm95403]

Can someone give me an accurate measurement of the front "china wall" part of the intake manifold width?

thanks in advance!

Thanks, but I meant side to side (distance between the heads) rather than front to back. I should have been more clear.

Alright, I thought you may be building a sheet metal intake and needed to find stock for the wall.
7 5/8

Actually, I'm looking at machining a set of spacers so I can bolt a small block Chevy intake manifold to a magnum engine. The Holley 300-263 for vortec engines would be much better than the Hughes airgap and the port sizes are very close to magnum ports. It also lets you use a much larger throttle body as well as giving more hood clearance. From what I've found, the sbc measurement is only 5.75" so plenty of room to make smooth transitions in the adapter plates. Now the only question is what to do with the back rail area of the manifold.

What about making a valley tray? Machine away the bottom of the chevy manifold, leaving only the side flanges. Thats how the big blocks and race blocks do it.

I don't think I'd need to do that, but ill find out as things progress

Another direction I'm looking at is to completely remove everything inside a kegger, runners included, then use a set of FAST lsx long runners instead
