Did some intake work this weekend. Truly testing my abilities (or show casing my lack of?), but as long as I can get the final product to hold vacuum and pressure I'll be happy with it. Plus a coat of paint covers a lot of sins, lol.
Also I didn't realize my error until I was mounting it up, but it appears I welded the last pair of runners upside down on the flange so they sit a tad lower, which has caused the plenum tube to angle downwards some. Not a critical flaw, nor do I think it'll even bother me once installed, just not squared up. On the positive side, it should allow more clearance for the throttle cable to come over the top of the runners from the firewall. Just tack'd together at the moment.
The tube is a fixed distance from the head, the front and rear ports are pretty much centered on the tube with the middle one slightly up of center. I've flared the ends and currently debating about how to handle the entrance. I see three options, 1) Leave it as it sits, 2) Weld pie shaped corners on, 3) Make a separate single pieced curved entrance to weld to the port pairings. I'm leaning between 1 & 3. I will probably try and give 3 a shot.
Needs plenty of clean up work on the entrance, but overall I'm satisfied with how it looks at this stage. It will be going on a ported head so the head lip seen there shouldn't be present on my other head. The other head is gasket matched, so I intend on doing the same on the intake if possible (shouldn't require much).
Also got these really slick steel injector bungs from CNC Dude Scott. The idea is to make a jig that will make it so the injectors will all be the same angle and use the same jig to drill the holes in the rail to make the rail fit easily. The issue I ran into with the stock intake was the injectors hit the throttle body/carb. This isn't the case, so I'm going to lay them over at least 45º. I haven't decided how close to the flange I'm going to put them since I can't reasonably angle them at the back of the valve due to the ports pointing away from each other in the head.
This is how a friend of mine did it on his big block Ford intake and I plan on doing something similar.
