K1 offers a 4.150 stroke crank with the 2.20 rod journal. so extra grinding wont be a problem when used with the chevy rod.
I would like this bb stroker to make peak hp similar to my sb which is 6800rpm.
with peak hp at 6800-7000 which would be the best crank to use?
Sounds like you want to build a B1 headed 470 ...

Hell a B-1 is gonna make peak above that point with
those cubes... if you didnt rev higher than that you'd
be leaving alot on the table

ok,i understand. would 440source be a good place to by good quality crank and rods from?

No!
I learned this the hard way: when you buy an aftermarket crank, send it straight to the shop and have the journals checked. Before you start scraping the bearings to make 'em fit.
My brand new 440 Source crank needed the mains turned .010, and the thrust was cut too wide (too much end play), so I ended up having to get a set of -.010 bearings with +.010 wide on the thrust.
Brandon may have got a better handle on stuff in the last few years, but the next crank I put in ANYTHING will go to a shop w/ an arnold gauge before I even think about using it.

489 C.I.D., roller cam, aftermarket heads, tunnel ram, stock '54 Dodge rear axle assembly: which of these doesn't belong?

after sorting thru all these opinions it seems most say go for the cubes. I guess if I had an after maket block it would be a no brainer,but i'm using a stock 400 block and have been told the longer the stroke the harder it is on the block.looking for durability here too. the 470 still looks good to me. so i'm still undecided on the 470 and 500. i'll have to just weight things out abit. thanks for all your help. 
The 400 blocks, all of them, are way stronger in the main webs than the RB or other B blocks are, way stronger  My pump gas 400 stroker, 518 C.I. with a 4.300 stroke has been used at the races and on the street for over 6 yrs. now, I did put a set of the Mopar Brand Ductile Iron main caps and ARP main studs in that motor, my current 505 C.I. bracket motor is a 400 block with a 4,25 stroke crank in it also, same main caps and studs as the 518 motor has. The decision is yours, it is always easeir to let the throttle pedal position control how uch HP the motor makes when you have to much power than it is to hop up a already built motor to make more power  1.37 HP per C.I. is pretty easy to make, no matter which combination of bore and stroke you decide to use  1.37x470=643.9, 1.37x505=691.85

I have a 498 and a 469 both 400 low deck motors. 498 drag race only 1.122" CH piston. 469 1.660" CH piston street strip car. The 498 rotating assmebly is light and helps it live @ 8500RPM. Street motor sees 7500 RPM once in while. With the heads you have either will work real good. Good Luck!

I think i'm leaning towards the 500. the peak tq should be around 51-5200 with peak hp coming in around 6700. should be a good street/strip combo.
you're as crazy as me I think
