W2 intake manifolds pics
I'm once again reviving this because I can't believe none of you cool dudes had one of these bad motherforklifters lying around.
The ultimate sleeper intake, an NOS P5249194, for your perusal.
Production-line 360 (and 318 cop) casting number:
It certainly doesn't look like anything special...
As you look closer, though, the details become evident. I've never seen an OE manifold machined like this for the center bolts.
Strange things are afoot at the Circle K regarding the EGR boss, too:
None of the accessory bosses nor the heater/vacuum ports have been drilled or tapped, including the coil mounts:
The boss atop the #4 port is required to install the OE '78-up axial AC compressor using factory bracketry once it's also drilled & tapped.
Port-matching was left to the end user. They used the stock LA cores for the runners.
Where they didn't use the LA core, and I wish they had, was for the heat crossover. That big pad? It's solid cast iron, as is any spot where there would've been cores for choke heat. This manifold weighs about 65lb according to my bathroom scale. It would require a lot of milling, drilling, and grinding to approximate the weight of its production-line 360 counterpart.
The weight is why I've never used it. When I bought it, I was loving the sleeper aspect. Picture it: A '78-'80 F-body or ex-cop M-body lightened as much as possible, with junkyard truck valve covers (all chipped up, big part number decal, the works) atop a pair of early unmarked W2s, with the AC compressor still in place, worked-but-dirty TQ, etc. To all the world it's the original 318 other than the headers. Such wonderful fun... Unfortunately,the armchair physicist in me just can't bolt something this heavy on a performance engine.
