Which Eddy for me?

lol @ the different eddy's. Definitely opened myself up to that one.

Lots of good info. I appreciate that. Seems to be a split here. Some say the 650 should be plenty. But others mentioning I will always wonder if I had enough if I opt to not go with the 800.

I'll admit I am no carb expert by any means. Say I went with the 650. How would I know if its not enough? Does it not get enough fuel under a heavy load? Like are we talking a possible miss during a high rpm situation?

Those suggesting the 800 - is the thinking here that its better to have too much than not enough? And that the 800 could be better tuned to my needs? Future plans include a different cam (mainly so I will know what exactly I have) but I probably will keep running the same (X) heads.

When people say its not enough, it don't mean after 650 cfm is gonna stop flowing fuel and air. It just will be more restrictive over an 800 cfm could cost you some hp for the choice. Think of it like headers 1 5/8 vs 1 3/4, even if 1 3/4 is the optimal choice 1 5/8 gonna give you 80-90% of the performance and probably better at low rpm and way better than manifolds. Same with 650 vs 800 you got 80-90% of the performance and way better than a 2 bbl :) You maybe only losing 0-20 hp maybe a little more.
