265 Hemi to efi

Looks pretty good after all those years

Cleaned and rebuilt and tested my second hand VZ v6 injectors and Getting those filters out we're tricky but worked it out in the end. My Spartan 2 O2 sensor and gauge turned up. Pretty much just need to sort out the manifold and fuel rail now.

Normally I just screw a self tapper into them and gently pull them out. New ones just push in easily.
Didn't realise the pic would come out so big.

[heff0018]

Yeah I tried that and it just wouldn't come out, it just kept pulling the self tapper out. It may have been that I just started with the one that was most stuck. I ended up bending a rivet over like a hook and that got them out. I then flushed them out with a pressurised syringe, carby cleaner and a 9 volt battery.

That's an interesting way to clean them. I use an ultrasonic bath and pulse them. Years ago it was a big thing cleaning injectors but our fuels and injector designs have improved to the point where it's no longer necessary. I haven't cleaned injector for a long time now.

[heff0018]

Thanks that's reassuring. I was thinking about manually cleaning the injectors on my Landcruiser but I just bought some injector cleaner to add to the fuel. Sounds like that should be sufficient.

I have a custom fuel rail coming from efi hardware and injector bosses from Ross macine racing. I have also decided to go with a 90 degree aluminium mandrel bend from the original manifold to the throttle body in the short term . Once I have done some more research I will take the plunge and build something custom. Hopefully cAn get the motor fired up soon

Keep the update photos coming

Looks like my custom landcruiser/valiant intake manifold may be back on the cards. I spoke to the welder and as your guys advised (THANKS), changing the cast iron manifold to cast alloy will make a world of difference. I have a second hand redline alloy manifold coming and apparently these are a direct copy of the original cast iron manifold.

Now I may have another problem, not sure. I have a set of steel bungs coming, will there be any problems epoxying these into a cast alloy manifold? My only concern is the different expansion rates of the two metals. Can any one see a problem with this? Cheers.

I'd get some alloy ones and get them welded in when the rest of the welding gets done, then you can sleep at night
