351 W Vs Modified 302

[whiterod]

guy's i have a dilema. My block has nearly 200,000 miles on it and i am thinking of the future. I am trying to decide what i want to do. I always wanted to put a 351W under the hood, but now i am thinking of keeping a 302 and just putting a little more on it. I have a few friends at the track that have supercharged 302's and juiced 302's and they run 11's and still get 20+ miles to the gallon. I guess my only doubt's of going with the 351 is having to buy new parts to fit the 351 like: lower intake, headers,.... and so on. And is the 351 as long lasting as the 302? What is the gas mileage comparison? Not that it makes a difference but if i can fly and get better gas mileage at the same time then i will take it. But i think the 351 under the hood of a fox is cool, because of the torque and so on. I know that back in the day cubic inches made the difference, but now days i don't think it is that necessary. what do yall think?
