a 4.3 V6 is a 90 degree, and I'm told that it's basicly a 305 minus 2 cylendars... so my guess would be 90 degree.

It's a 90* motor, just like every single small and big block motor in the history of Chevrolet.

Jim85IROC,

Got that right! Buick made a 60 degree V6 thats common in several GM makes.

The 4.3 has a 4" bore, so you could call it a 350 with 2 cylinders chopped off. All SBC, (the 4.3 is a SBC too), are 90* engines.
