My 455 in my '68 is in need of a rebuild. I drive my car everyday in the Summer (8-10 mpg and $3.30 gal for premium is no fun!) and due to the current and future state of gas prices, I'm entertaining the idea of going w/ a Pontiac 6 cylinder engine. Since I know little about them I was hoping you all could help.
1. What kind of hp/torque could one expect to get out of a 6 that will need to be reliable but fun?
2. How much do they weigh vs. a Pontiac V8?
3. What would be involved in swap from my current V8 to 6?
4. I currently have a T400 trans. Will the 6 bolt up or should I have a dif. trans?
5. What Gear ratio should be used in a fgf for all around driving?
6. Expected gas milege?
7. What should I expect to pay for a rebuilt engine?
