Hey guys,have been sorting out which way to go with my EA 3.9 cfi sedan,as I mentioned in my build thread for the ute i was going with a cms stage 3 cam as i have all the other bits springs vernier cam gear collets etc,but i have a EF engine with auto still atached (approx:250,000) from running car and I was thinking maybe refreshing the head and gasket and using the EA cfi camshaft with the vernier cam gear set up with BBM EL ecu & J3,what I am wondering is what associated parts I need to change as well-will be going to a dissy of course but should XR spec springs be used instead of standard? and would going 5 speed manual get a better result compared to the auto with this combo? stupid question i suppose?

p.s will be changing diff gears 3:45.1 lsd.

Would love a bit of guidance with this one

Never mind!-shall sort it out,more to the point all i wanted to know is,is the CPFI camshaft the most aggressive cam profile in stock form for the MPFI 4.0 L?

going by memory [lol] ... think something along these lines was brought up once ?? ...... believe the answer to it was no

Yea wasn't sure-vaigly remember reading something about it but I think I'll use the XR cam for now

yeah i'm only 'vaguely' remembering it too

Nah 'waigely' can someone tell me when (what year) they went from 14mm HLA to
11mm HLA?) Is it just EA/EB?

Just working out what heads I have that take 14mm to later Eseries heads taking 11mm,I have lots of Ford 14mm HLA's,I have used other Nason products but never the HLA's-anyone had any problems with them?

Nason are fine.

EA/EB/ED 14mm.

EF/EL/AU 11mm

Thanks SWC-I am just in shock with Ford-will use Nason unless I go with the stage 3 cam.

You use the same lash adjusters with a CMS Stage 3.
