RB block 4.350 bore
4.250 crank with 2.200 pins
6.800 Chevy rods
12.5 CR. (Diamond flat top shelf piston at zero deck)
Indy EZ heads with CNC porting by Modern Cylinder Head
Indy 440-3 intake or 440-2 with 4500 adapter
1050 Dominator carb
Flat tappet cam about the size of a MP .620
2 inch headers
Torque peak should be around 5200 rpm with power peak around 6200 rpm.
i'd use a dome piston for around 14:1cr, and std EZ-1's with some minor clean up/valve job corrected, and more than likely a roller cam.
the cost of the roller set-up or the CNC porting is about a wash....and i'd rather just invest in the roller cam right off the bat, then have the heads ported later on down the road.
with a roller and 14:1cr, it would make over 700hp with ease.

My build is very similar to the one proposed by AndyF, target for the build is 700 hp @6500. Still waiting to get on the dyno, should know for sure in November. Similar build with less compression in a friends ride was 675 hp.
440Rb bored 4.350
Ross flat top @ zero deck 12.3:1 CR
4.15 crank
oiling mods
milodin external line setup
roller 280 @0.050 700 lift 108 LSA
Indy SR ported to max wedge
440-2 intake
1050 dominator
Super Comps with collectors
76 Duster
work in progress

Whats a bare set worth.??? I was just making a contribution to the thread, I'll be using B1's on my 511 build...!!!!

a bare set of regular edelbrocks is around $1400.
a bare set of the 84 cc big block heads is under $1200.00

... I'm a member the default 700+HP combo group wannabe's. My next move will be to move from a 440 to a stroked RB.
Same here.

... I am wondering if a flattop piston is do able with a 65cc combustion chamber and pump gas?
No, but that's where a dished piston fits the bill quite nicely.

you could add some small domes to the pistons to push the CR up to 13 or 14:1. With that big stroke you only need a tiny dome to really crank up the compression.
On my 4.250" stroke, 4.375" bore engine, I calculated 13.2 CR just by milling the heads to 71cc. So, depending on your chamber cc, piston to deck, etc.; a small dome can get to 14 CR.

Ok...while we are on the subject. If I wanted to make say 675-700 for my Arrow...what would be a good combo? I have max wedge ported SR's and a Indy intake to start with. I would need a complete short block...less oiling system and balancer. Car weighs 2354# w/driver. I have a Coan 8" 5500 and 4.56's......Goal is 8.80-8.90's 
Dude... If you just continue with your plan within your signature, you should be good to go!  Chuck will do you right!!!

I'm pretty sure they are refering to the Victor heads, not the Perfs

--------------------
"Me and my Arrow"... 6.078 @ 113.56 in the 1/8 9.582 @ 140.82 in the 1/4 so far...still planning on a 500" Best Machine bullet
This is how I look at it.
You want to go 0.70 seconds quicker and at that ET it will require about 140hp more to get there. Put a 4.250" crank in it (511 CID) and stepping up from the 446 CID is worth around 1.3 hp/CID x 65 = 85hp. Up the compression ratio from 12.0? to 13.5 is worth 1.5% x 650 = 10 hp. A better roller cam should be worth another 30hp. That leaves 15 more hp to find. Some additional head porting might be in order. I would also like to see some 2-1/8" headers on it. The bigger motor will need your torque converter tightened up as the stall will go up with all that torque.
Looking at it another way, my engine/car at 3160 lbs went 9.32 in 500 ft DA air at Norwalk last weekend. Your's is 800 lbs less. So my combo would put you at 8.50s in that air. Good flowing heads are important (350 cfm or more).

I`m also reading and dreaming. But here is the question I ask: How do you take a stock block that is considered "marginal" at 600HP,and stuff a 4.25 crank in it and bump power up to 700+ and still sleep at night? I understand all the terms like----- good assembly practices,"good" machine work,quality parts etc....... But isn`t this the same group of people{myself included} that consider a stock block a "bomb"?
Besides filling the block,what are you planning to do ? And how long do you expect one of these to live?

For long life, light is right! Take pains to get the rotating wieght down as much as you can to keep the stress off the block. If you are lucky enough to secure a center counterwieght crank, that is a big plus, as it places the forces more opposite of each piston/rod pair, reducing stress by a fair amount.

It would be interesting to see how that combo of roller cam and std EZ heads would work. The only motor I built with the std EZ head didn't really work out so well. Once I had the EZ heads opened up to max wedge size they took off. But I'm sure if a person played with those heads a bit in std form they could be made to work. There are a lot of fast cars with heads that are worse than a std EZ!
I plan on upgrading my combo this winter with the 295 "Little Easy" CNC heads along with a small roller cam. My shortblock is a stock stroke 440 +.055 with Ross Flattop pistons. Heads will be cut down to abbout 65cc's.

alum caps , maybe the rods ??? take as much stress out of the webbing as possible and it will live longer , but i bet in the end ....
