I was watching an episode of Roadkill (Extra) and Dave Freiburger was asked about GTOs in terms of cars he likes. No secret, he's a diehard Mopar guy and also seems to like Fords and Chevys.

He said he NEVER liked Pontiac engines because they have a "design flaw in the lifter valley". Does anyone know exactly what he means by this - and is he right? How does it affect performance? I know the classic issue with Ponchos is head flow at higher RPMs (although the result of that limitation is low torque which is the Pontiac secret sauce on the other hand).

Also, he said GTOs are "just okay, they're just Chevelles".

As a Poncho lover (and I love Mopar too), I never understood why Roadkill hates on Pontiacs. Sometimes, to be fair, Freiburger will acknowledge the 455s but says the Buick made more torque. And Finnegan at least confessed a love of Firebirds as a teenager (there's an episode with a white Firebird that they end up, gasp, putting a 350 in).

Just curious about engine design differences among the great big three.
