Need confirmation on some 69 GTO specs

[Don_Lightfoot]

I had a very nice 69 GTO for a few years in the mid 1990's. It was the base 400 CI with four speed. Got into a recent discussion with a fellow enthusiast regarding some specs of the 400 CI engines. Unfortunately I can't find all my GTO reference material.

<u>Here is my understanding:</u>
- Although they both had the 350 HP ratings, I believe the base engines had different heads and cam between the four speed and automatic.
- It was also my understanding the cam and heads for the base engine with a four speed were the same as the RA III setup.
- The RA IV setup moved up a step from there.

Carbs and intakes we're not concerned about. Does this guy owe me a beer? Appreciate it.
