what do u guys think of this?

I think for what you're doing the Source crank and Eagle rods are the bottom and middle of the road respectively. I would not expect much for longevity if this is a race engine. What I see wrong in terms of parts matching...The intake should be either the 440-14-3 or the (-3x). You need a 4500 carb pattern with the max wedge port window and some volume. The M1 is not even in that league. If this is a street car I'd go with a full custom Dominator from Bigs that will flow 12-1300cfms. For the cam, Comp has some fast rates that work well with 1.7-1.8 rockers but they are brutal on valve springs and you'll have to check them yearly. BTW, no way in hell should that 8 3/4 be in there. Get a Dana 60 w/4.56s or 4.88s. If you want to make 700-800hp reliably I would at least upgrade the crank to a K1 so the journal finish is perfect.
