Here's what i'm looking to do. I want to build something that will put me in the solid 9's. would like 13:1 and solid flat tappit with indy ez or 440-1 depends on header fitment into an A body. Ordered the main caps and girdle kit from Jerry for my 400 and would like to get the machining done this year,the rest next. this motor will be detuned and run on pump gas once I hit the 9's and will do street/strip duty only. what would you build 470 or 500? http://www.youtube.com/watch?v=aIxaesJ190U http://youtu.be/lCZAaN7fFLg

That's a no brainer.... but since you already have the 408 (not sure of the combo) you might be ahead of the game to stick to it and make some improvements. Going big block will also end up with a trans change, and more than likely a new torque converter purchase which will factor into the cost of the build. Our big block is gone... and we're sticking with the small block. Not sure why....but we prefer it that way
