Not too much of an update. Mostly just collecting parts. AN plumbing is expensive, but I think I have everything I need except for the fuel rail fittings now. Im also hoping I can clear the hood at this point….
The intake/throttle body/spacer/air cleaner stack is pretty tall. But it had to be to clear the rails with the linkage on the throttle body. Only other option is to try and modify the throttle body by removing springs and shortening shafts. Or, ditch the 4bbl throttle body all together, and run a 454 TBI setup with the injector pod removed. Supposedly flows about 780cfm that way. We’ll see what happens when it’s all bolted together.
I also need to make rail hold downs. I’ll do that in the near future after the intake is painted, and everything is put together with wiring, etc to see what I have to do to clear stuff.

Lastly, I rebuilt and cleaned the 30lb injectors, as well as did some math. These are rated at 30lb at 43.5lb of fuel pressure. At 60lb, they will flow 36lb, which should be enough for 400rwhp. In theory, at least.
So we went from this:

To this:

I think well be ok here. Worst case, I’ll pick up some newish 36lb injectors, and swap them out.

Lastly, I guess ill throw up a for sale ad here. I will no longer need the Holley blue pump, regulator, 750 edelbrock carb with electric choke, electronic ignition distributor, and pro-comp air gap intake. Figure a screaming deal at 300 plus shipping obo. If anyone is interested…..




Next up is painting the intake, modifying the spacer for some vacuum ports, mockup, etc. just chipping away at things.
