Well fitting the VK EFI manifold will require a 12-port head and suitable flanges on your extractors as well. It's not a whole lot of work, but you already have a ported head with big valves etc and you couldn't use that stuff with the VK EFI setup.

Then EFI systems (in general, not just the VK setup) need a different style of fuel system with a pump at the tank and a high pressure line, a return line etc which you don't need with a carbie obviously.

So unless you have a good reason to use that setup, which isn't a particularly impressive setup, I would just suggest sorting your SUs out. I think you could probably get them to at least provide equal fuel economy and potentially more impressive performance, but that really depends on a lot of small details... and how willing you are to get the combination sorted out well.

Ohh yeah and triples sound awesome

Did the person that told you to do all this offer to help out with $$$ and time?

thought not.


Fix the triples I say....are we just talking rekitting them? or something else?

I put a VK EFI into an LX years ago, and the manifold stuck out the bonnet. One of theose "bugger" moments.

In all honesty, most of the time and effort is in sorting out the fuel and wiring. The same amount of work is required for any EFI engine, so if it were me I'd go buy a complete VN-VSIII EFI 5L. Much easier fitment, bolts straight into a UC with sump and pickup swap using Torana mounts. And you will be able to buy a complete running engine with all bits for less than $1500.
