ive heard from a somwhat questionable source that the 250 i6 has just as much torque as the 302. not sure if compared to efi302 or carb302.
Rooster, Check out this site: http://fordsix.com/tech/index.php I am building my 74 Grabber and 63 Ranchero with I6. The Grabber will be my hot rod. A new aluminum head will be unveiled any day now. Can build a 250 I6 for up to 300HP. Stay inline and practice safe six.
i saw an article about a falcon with a 6 turboed pushing 350hp which was awesome, but i was a little more curious about stock ratings. i will say i do like the six alot more than the 302 only because the efi isnt as user friendly to me as carb ran.
