Pushrods in big motors, OHC in little motors. I think the OHC engines get the nod for high RPM use but pushrod engines make a better powerband. Basically for something like drag racing I think the pushrod engine has a big edge because they make so much low end power, but for some kind of all out wide open racing I think the efficiency of the OHC engines is going to take the cake.

Yah, but it's a half~hearted attempt. Not that it isn't a good motor, but compare that to an LS1 with the same SC and how much power would it make, or compared to something like a HP import engine or Motorcycle. 1400CCs and almost 200HP. GM didn't really take full advantage of the OHC on the Northstar.

MB's 5.4 supercharged engine makes the same power with 1.0 more liter. Not saying it was a sad engine, its a monster, but the Northstar is somewhat still relivent considering its a 15 year old design....
The new Ultra V8 should bring the GM OHC V8's up to spec with the new BMW and MB V8's.

Point well taken, I forgot how long it's been around.

An extra overhead cam definetley makes a bigger difference in those little 4 bangers than in the big V8s
