Jenvey heritage 45s are the dream. Only one way to find out.... Id run legit injectors though not China spec ones (assuming it comes with them) 2 Quote
Bearded Baldy Posted July 24 Author Posted July 24 Yeah would not be using aliex injectors. I really only need 45mm throttle plates, as the xf manifold has a thin seperate section with the injectors in it so i could make an adaptor plate up between injector section and whatever ends up supplying the butterflies. Picture 6 small SU carbs with no innards. But bugger balancing 6 links. 4 Quote

Bearded Baldy Posted July 27 Author Posted July 27 Good to know. These turned up today, the A pillar piece and the inner quarters were unpainted. So i grabbed the closest rattlecan and gave them a quick spray. 2 Quote
Bearded Baldy Posted July 27 Author Posted July 27 This is the injector plate for the efi falcon manifold. Looks easy enough to make an adaptor plate for, but what should i adapt? As a bare throttle body Jenvey recommended 45mm, so i am thinking something with a bore of 42 to 45mm should be sweet. Or i can take the sensible route and just buy a triple dcoe manifold as they are still available. Will be a long way off either yet. 2 Quote

Looks easy enough to make an adaptor plate for, but what should i adapt? I can't remember if you've mentioned it or not, but the Iron head on the XC has a different intake to the alloy, has a water outlet under number 2 intake port. I bolted an alloy head on an iron head once, I was told it wouldn't work (it did, but the locating dowels needed to be be binned ..none in the block on XC) I didn't use this engine for long, but it was a good combo of pre pollution cam, probably higher compression with the mix n match.. but smoked and burned oil.. was one of the most powerful stock crossflows i ever had though.

Bearded Baldy Posted July 29 Author Posted July 29 That is correct @deankdx, i have a complete xf efi engine with E2 head sittingnin the back shed. Will get a swap done on the heads one day but panelwork is more important at the moment. Can't hurt looking into morr options in the meantime though. The E2 chambers and the chambers on the ironhead will be near enough the same cc once i give it a massage with the grinder and get it skimmed. 1 Quote
Bearded Baldy Posted August 2 Author Posted August 2 Going through my notes i found these part numbers from when i last had the head off. Posting here as backup. 1 Quote
Bearded Baldy Posted August 7 Author Posted August 7 Well shit. Took the alloy driveshaft into work today to split the flange and yoke for painting and polishing, and noticed this once it was all apart. Seems it has corroded from the inside out. Have never seen it happen before. The guy i bought it from has been real good, i need to measure it up then he will track down another one. Good to know there are still good bastards out there. 6 Quote
Bearded Baldy Posted August 12 Author Posted August 12 Middle ports kind of kill the idea for an adaptor plate. 3 Quote

Bearded Baldy Posted August 12 Author Posted August 12 Cheers Dean, i forgot the plenum came off the tubes... More to consider once daylight returns.... 1 Quote
