740 & 760 Cam swap in a 1987 740
I've got a 1987 740 with a B230F. It currently has the M cam, but i have a good used condition VX3 cam.
Recently i met a Volvo engineer who actually told me it won't run right as the VX cam wasn't made for the B230F and i probably shouldn't swap it.
Is this true in a real life scenario?
The M cam is a bit boring and i'd like to get a bit more power, but i certainly don't want the car to run or idle worse.
