All new LS2 car from G.M comin' soon

[allmotoronly]

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?

Theres no reason to say that they would sacrifice tq with a DOHC design. The only reason that most V8's with DOHC have low torque is because they are also much smaller in displacement than the pushrod GM V8's.

I have also heard that the newer northstar engines have less problems than the old.

anyways, my point was that if GM could team up with toyota or honda or audi or bmw or MB or Nissan and design a good DOHC head design and redesign the current V8 blocks so the heads will fit, then they would make waaaay more HP and be able to rev higher as well. Honda has made a prototype v8 in japan. it was 4.0L and made 590hp N/A. I know this was just a prototype, but in street trim this engine could easily make 450hp. Audi has the 4.2, BMW has the new 4.0L.... they all make over 400hp easily. GM has to have 6.0L or more to make 400hp. AND GM engines have lesser fuel economy.
