I'm in Essendon. The extractors that i have sweep too far back. I was going to have a set made up. The guy said he could fit them thru, its a gap of about 125mm. He then started on about getting a plate made up to bolt to the head...etc and I thought I'd take the easier/cheaper route. Its only a round port head and I'll be running a single 45mm dellorto. I have a 5 sp. o/d box for it. Even if I use a cast iron manifold, the pipe will have to drop vertically down as the back of the motor its far off the firewall. I would be interested in seeing what you had.

That mid sump model would make the mods required much easier. The one that I had modified has been superseded. I am yet to cut up the new one until I locate a donor sump that will give me plenty of capacity.
