My 470 is quicker and faster than a lot of those 500+ strokers and a beast on the street w/good old home ported rpm heads and a .680-.660 solid roll in the mid 9's plus fully street-able.....Fit's better in most engine bays as well....

More info needed, such as...
- Auto or stick
- If auto, converter size & stall
- Gearing & tire size
- What parts you are starting with
- What parts you expect to keep
- What parts you're willing to replace
- Minimum fuel octane requirement and/or expected CR
- Track-only or street/strip
- Header size and exhaust requirements
- Hydraulic, solid flat-tappet, hyd roller or solid roller cam
- Car + driver weight
- What does the car run now, and with what current combination
- Approx. altitude of local track(s)
- REALISTIC BUDGET

Simpler to just stick w/ a 440. ABSOLUTELY. Need more info also. Street only ? StreetStrip? Bracket car? I am in the 9.70"s with a .030 440 with average heads .590 MP solid 6bbl. on 93 gas.But it's only 3,000lbs. Strokers are an attractive nuisance LOL. If starting with nothing stroker is just as cheap. Budget build...decent piston and rods STOCK crank and go...

For a “race car” of reasonable weight, 10’s are a piece of cake.
Every consolation made for the sake of “streetability” will usually cost you some ET.
Thats where the bigger cube strokers start to make more sense.

Unless you already have the 440, The only things that strike me as easier with the 440 is sourcing the crank and intake choice. After that, almost every advantage goes to the B version.
If you’re going to start from scratch with either, intake selection would seem to be the only advantage to the 440, and that’s really only an issue if you’re working with Maxie port sizes. The 400 version is going to weigh less, it’s going to fit easier, it’s going to be marginally stronger in the bottom end, rotating assembly is lighter & bore size is going to be a little bigger so it should rev faster and make a little more power. Less weight up front makes it easier to transfer weight.
I vote for the B version. But I am admittedly a little bias since I run one. My car was an original 383 car, so I wanted to keep the orig look. Truth is you can build a really great 10-second B Body with either.

The big advantage of using a good sonic tested 400 block is that you don't have to worry about cracking the main webbing like you do with a stock 440 block  I've seen 3 RB blocks with crack main webbing and read about a bunch more of them from guys on here Think twice, build once  I've built a bunch of 400 block stroker motors, if your shooting for north of 650 HP on pump gas invest in a good set of main caps, I like and use the aluminum ones with ARP main studs from 440 Source now

Stealths will give you low 11's with a mild street build with "normal" street car weight and all the compromises that come with it.
Spray your way to mid 10's with a 150 shot and have something that you can drive to work every day.
