I've looked at a ton of dynos and consistantly there are about 4whp difference between a sohc and dohc, granted I was a dohc flag waver and still am but thats not that much difference to make me want to swap a head or motor on. The difference on the dohc is that its2 camshafts andintake aretalored to run high speeds while the sohc's cam is made to run the low-mid range, like Jeremy has said with the dohc and sohc motors its a give and take in stock form, sohc for low to mid power and dohc for mid to high end power. I wouldn't want to rev one of these motors past 6,000 Rpm in stock form, I've heard of rods flying out and just a range of **** I wouldn't want to clean up on my daily driver unless I had a full race balance on the pistons and rods and crank.

There are people with sohc engines that run 7600 Rpm with the right cam and intake,thats very much near the maxpoint anybody would push either of these motors seeing they have the same bottum end.

I've always said both these engines are good and either engine is only limited by what the owners imagination and budget is. To quote a saying from Jeremy "its ricer Math to believe each engine all over the country no matterif its built the same or notto have the same power with given parts because there are too many variables to say each will be consistant.

So to that you could say that 4whp averageis in a margin of error point where any sohc and dohc car could suprise one or the other on a given day at the track.

Paper statistics would point to put your money on a dohc equiped Neon in a race against a sohc Neonbut with a 4whp difference in these engines it depeneds on more than what these engines make for power since they are so close.
