...I know your looking for more, but just thought I'd throw this out.....
Messed with a couple by doing 3 things:
1. Cut the head .100
2. Added the super six (2bbl intake and carb)
3. Exhaust manifolds have different exit holes. Found the bigger one and ran 2 1/4 exhaust.
Both responded very well and really couldn't tell it was the same engine. The one was in a '72 Duster that we threw 3.55's behind. Even with the stock converter, it would turn the tires very easy.
Never took it to the strip, but we did line it up against a Dynasty 3.3 I had at the time that ran 17.27.
Before: The Dynasty beat it by about 4-5 car lengths.
After: The Duster smoked it so bad you couldn't even count the car lengths.
Conclusion: Nice, nice gain for spending about 200 bucks.
