F4R 736/770 what's the difference...

[flaffy_91]

can anyone tell me the actual difference between these two engines.
I know the blocks themselfs are the same.
But are the internals?

And I know the heads and valve train is different also, but do they have different sensors/wiring or would this also be pretty much the same?

Any info would be good. Thanks chaps.

No ideas on internals or wiring etc etc but I believe the 770/771's produce less hp (136 from what I've read), if it wasn't 3am I'd fire up auto data and have a look for you

Yer I know power wise it's less aswel.
Just wanting the know the exact differences if anyone knew them. But of a project coming up and I'm wondering what parts to use.
Mostly just down to wether sensors are the same or not really.
