Red Rose or leave it Satndard 4.0?

[Snaaakeey]

I'm taking the plunge and having the engine rebuilt. I plane on getting the R.R. cam ( its a standards 4.0 2002) but some have suggested that its less drivable with a peaky narrower power band and possibly its idling and road manners aren't as good and to leave it standard. My counter is that the R.R. cam is standard on the rest of the range ( mk2 /s ) so it cant be that bad!

Your thoughts please.

Sorry meant cam timings.

Didn't thing R.R. was bigger injector though. Does the compression change too with different piston crowns? I thought these changes where just for the MK2 /s.

Please fill in my missing knowledge!

So Im finding conflicting info on the R.R.

New pistons ( 1mm dish)
ECU flash
Cam timings
Bigger injectors (???)

I guess what I really want to know is does anyone have 1st hand experience with one and does the extra hp have a drivability trade off?

Interesting ECU info.

[Snaaakeey]

Aye.

This is in the TVR lore.
