I've heard a lot of bad about the 4.6 sohc. I heard that it can't hold a lot of power without blowing up. Is there any truth to this? I'm looking to do a swap from the 3.8 to the 4.6, and am willing to spend the money to get it up to around 600hp to the wheels, however, I've heard that the sohc 4.6 tends to blow up when you get that high. That doesn't sound like a very good v8 motor. Anyhow, I was thinking about getting one used and rebuilding it with better parts. Would that making the death of the motor less likely? And what brand of parts should I use? Are the "Ford Racing" parts (ie pistons, heads) the same as what's already in it, or are they better than the stock ones? How high can you push the sohc 4.6 before you have problems? Thanks guys!
