Is you Wife or GF driving your race car?
Lets see...... a typical decent built bracket engine ... Nothing fancy but good stuff 1.6 hp per CID
408 = 652.8 hp
557 = 891.2 hp
Is that answer enough? Do you think an extra 239 hp will make up for the extra 100#?
using a wallace formula
652hp @ 3000# = 9.69 @ 138
891hp @ 3100# = 8.83 @ 152
Hummmmm........

The formula demonstrated the difference in weight from going with a typical 351W based fox to a 460 based fox. assumin a 100# weight difference between the two.

That wasn't your question.......
Fact is the Typical Bracket 351 will only do it with NO2 and the BBF will do it N/A, even with the added weight.........

What can you build a real 650hp NA 408 for that can handle a shot big enough to get you to 8.99 @ 3000#?
