Is RWD timing different from FWD? Cam Lobes tdc

At tdc cam lobes point?
I would like to ask what a 2.3 duratec is at tdc do the cam lobes point opposite each other, ie, almost level to the deck... My cam gears lines are pointing outwards opposite each near the prescribed angles.

Is a RWD timing different from a FWD?
I have keenly eyeballed the tuning kits available for the 2.3 Duratec but my cams have no slot on thier ends, instead, half-moon cutouts and there is no crank stop pin hole in my block, the molding is there but no hole.
engine is in a transit

Cam lobes straight outwards for cyl. 1 tdc compression stroke is std. for all twin cam 4's.

I can't guess at what other differences for your engine model.

If your cams are keyed to the cam gears, the lock plate & stop bolt are less likely to be used, as it sounds from your description.

Any timing marks on the gears?

thanks for that sailor,
the cam gears do have timing marks and are keyed but the lock plate would be handy getting the chain right (for the unppractised)

Yep, i undid my crank bolt, now it's tricky finding tdc.

On our versions undoing the crank bolt also looses the timing at that end, it's only held in position with special diamond coated washers & the tension from the bolt.

Got a keyway there? For us a keyway on the crank is only avail. on aftermarket modified cranks.

nahhh, No crank/cam gear keyway in the colonies either...
i have read there is a pin that goes into the rear block of the some engines to pin the cranks tdc but the gbox had to off to access it...

early on i got excited cause i seen some yello crayon in one of the fly wheel teeth but when i put me glasses on it was bright rust instead...i suppose ill have to stiif around guessing it, use the fluid method or buy a dial guage to find tdc...

Use a dial indicator in the #1 spk plug hole to get TDC , In most cases I use a screw driver and get the #1 piston all the way up where when you move the crank the piston/screw driver doesnt move and thats TDC

Washer should be between timing chain gear & crank to help hold that gear securely.

IIRC I saw mention of some with two, one on each side of that gear.

If the cams are timed right the #1 cam lobes should be pointing at each other on tdc.
