Rover V8 alloy rocker covers wanted

[churchill]

My brother in law has an FJ40 with a Leyland P76 V8 in it. We've fitted a Lucus 14CUX injection kit and want to get rid of the pressed steel rocker covers. Does anyone know if the Rover V8 alloy ones fit and if so, does anyone have any for sale?

[nakimud]

Yes they do fit, if you havnt found out already! what covers are you after early deep finned rover or later rover covers? how did the 14cux work on the p76?

[churchill]

Ended up getting some early Rover 3.5l ones that fitted as you mentioned. We've got the 14CUX fitted, had to make up some spacers but that wasn't too tricky but time consuming. Haven't wired it up yet but it seems relatively simple as a system so don't see to many issues ahead of us.

You might find with the 3.9 14cux setup that it runs a little rich down low and lean higher in the rev range, I have rovers/p76 parts and a manifold with spacer plates, if I were to do a p76 14cux I would run an independent fuel pressure regulator and bump pressure up to 38-40psi and run the ford bosch injectors(fit straight in) I have the part number somewhere (4.6 ford) They really hammer with the injection tho, good luck!

Interesting about the mixture, what tune resistor was that running?

Whats the reason for the injector swap and upping the fuel rail pressure?

[nakimud]

470 ohm(I Think) non cat non lamba, I had wondered if a cat tune w/o cats would be better on a 4.4 due to the enrichment required for cats? injector swap was to get the 4 jet injectors as opposed to 1(rover) just seem to run better they flow the same lb/hr and pick up a small amount of economy! increase in pressure will help overcome the 500cc+ increase in displacement with the leyland

I see, so higher quality spray pattern with the injectors. I assumed that the computer would measure the intake air mass and fuel accordingly, there was that thought in the back of my mind that if anything was purely RPM/displacement based we would be in trouble...

What did your engine go like and was the 14CUX reliable?

I've noticed that the dizzy we have has no vacuum advance and the 3.9 does, what setup did you run?

[nakimud]

Yes the computer does measure the afm and fuel accordingly, but remember this is old school, the 14cux has 6 fuel maps on its chip(determined by resistor as to which one it uses) and its fuel tables are pretty basic and fairly conservative(as the 3.9 14cux is lean enough at cruise). The 14cux is in my opinion some of Lucas's best work as far as reliablility go! pretty damn good for what it is but it is pretty crude. I used an original crappy p76 distributor with a pertronix conversion, and only because it had been scoped and tidied up. Do you have a Mallory or the like with no vaccum advance? if its total advance suits the p76 motor (30 odd degrees) then I would just run with what you have, if it ran good with carbs itl be sweet on EFI

[churchill]

It look like the standard dizzy but it's been fitted with a Luminition constant energy ignition system, e.g. optical pickup and ignition module. No vacuum advance... won't be cruising much so hopefully this won't matter....
