So what should I expect from this combo?? And what cam should i use?
 
Thats a good combo your starting with. the gear may be a bit much, id say a 4.30 with that tire. are you gutting the car to get it down to 2700? If this is all correct id say low low 10s or an easy mid to high 9 sec.

Also it aint going to happen whithout moving the springs and going with a ladder bar or cal trac set up
 
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.
 
No doubt an Indy intake. i have the max wedge port standard 4150 with a 4500 Adapter . i know folks have there complaints about Indy cylinder head but i never had any problems with cutomer service, call them and explain what your wanting to build and they can recommend the cam and related hardware. if you go with a 4.25 stroke your adding a lot of torque leverage so i would be concerned with the gear you choose
