Default Re: Ram Air IV versus 455 HO

As far as the LS6 goes... Chevy has the best heads for breathing period.
Problem 1 is the 70' LS6 weighs 3850 lbs, that doesn't help
Problem 2 is the intake manifold and the exhaust manifolds are choking the engine's breathing capabilities.
In other words they s*ck.

Chevy knew people were going to take their cars racing, and throw away the intakes for better ones and throw away the exhaust for headers. Once you do that to a BBC, you got a whole different animal. A car that most brands would have a very difficult time beating.

Pontiac GTO on the other hand, was a super cool image street machine. Pontiac was selling boatloads of GTO's while others were selling 1/3 as much most of the time. Chevrolet had 3X the dealer network and 4X the advertising budget as Pontiac and still couldn't out sell them!

Pontiac built good heads, excellent intakes, good exhaust manifolds, topped with great responsive Q-jets. And very little work was required to turn a showroom car into a "street cleaner". On the street they were tough to beat, but were never meant to be all out drag strip racing engines.

Ok, thats enough of a rant.
