They should try to find some honda or toyota engineers to help them design something that hasn't been around since the beginning of cars (PUSHRODS!!!). Cadillac Northstar DOHC variable valve timing 4.4L 469HP FTW. Cadillac is being stingy with the technology. If they would share with the rest of GM, the Z06 would have 705hp instead of 505hp.

caddy's northstar motors are incredibly unreliable. call up cadillac-jaguar of northlake and ask them how often they're replacing a northstar. i promise he'll tell you at least one per week.and thats just in the little town of tucker!

also if gm went with dohc instead of cam in block, they'd be sacrificing a good amount of tq. this means they'd have to spin the engine to higher rpm to achieve the same hp.

can someone find me the equasion of tq+rpm=hp?
