stock stroke 440 (a stroker would blow your budget) & much better yet a 400 with a 440 crank (451) or offset ground 440 crank (470). 440source alum heads which wouldn't cost much more than doing a set of 915's & shoot for .040" quench which'd let you run the most CR/ign advance on 87 octane. that way you'll have the most efficient long block that you can possibly achieve with nothing left on the table that could have been had with better planning (in other words no open chambers & take the time/$$$ to get quench)  .
live every 24 hour block of time like it's your last day on earth

I'm tossing ideas around for my upcoming project. It is a '71 340 Road Runner that is missing the original engine and tranny. Since it will not be #s matching, I think I will go with a 440, or stroker engine. How difficult will it be to reach these goals with the '71 B-Body? What would you recommend for the engine build? I'd prefer to keep the budget as low as possible while still meeting these goals - what should I expect to spend?
1. I'd like it to run 12.90s or faster
2. It must run on 87 or 89 octane. Nothing higher is available where I live. The 89 is 10% ethanol.
3. Must run cool and be streetable for cruises and possible long hauls.
Thanks
easy goal. 9:1 440, fresh heads (ported would help), 490-500ish cam, RPM intake, holley 750dp, Headers, 2800 stall and 3.91's will give you a 12.90 car all day.

You could do that with a smallblock stroker with Edelbrock heads and have a much more driveable car.
Also you'd have more room in the engine compartment for things like headers.

I've thought about that too - keep it looking closer to how it came from the factory.
Just thinking of my options right now.

What is your maximum budget? The best year blocks have the distributor on the front.  For heads, you will need a closed chamber and the options are, in order of desirability, the one year only 1967 915 and 516 which was on all the earlier engines. IMHO unless you have a set of these in stock, it will likely be a wash $$$wise to just get a set of 440Source or Edelbrock RPM's. Ted's option might even be cheaper. Kevin

Don't have a budget set yet, but I'm thinking of starting to accumulate parts as opportunities present themselves. In other words, the budget may be $2K or it may be $5K when I'm ready to build something.
It's likely to be somewhere in between, probably closer to 2K than 5.

BEE ESS you'll need more cam, more gear, more head work, more converted and a special crank, pistons and all for the SB. You'll have twice as much $$ in the SB and still won't beat the stock stroke cast piston, iron headed 440.

Agreed...
Have a similar set-up under the hood of a '71 Ply B-body...

See my sig....(12.20 motor) Basically what you are wanting to do. I have run it on 87,89 and 91. I race it on 91 to be safe. I "think" it would be fine to run on 89 all of the time, but I do not know that for sure. The compression works out to be right at 9.5. I might shoot for closer to 9.0 with tight quench. Dont think you need fancy heads to get what you want. As my sig says Im using bone stock (cheap valve job only) 346s....Comp XS282S cam..Very basic. Last time to the track it pulled left front 2-3 inches. Right front was barely still on the ground. Ran out of fuel about 1/8 miles cuz the tuner (me..  ) forgot to put a notched float in the rear bowl. Let off at a hair over half track and still went 12.57@ 85..So, it MIGHT go a high 11 it sits. Very very vanilla basic combo..but runs nice and drives beautifully on the street. 
72 RR, Pump gas 440, 452s, 3800 lbs, Corked, ET Radials,. 11.33@117.72.
Same car, bone stock 346s, 9.5 comp, baby solid. 12.24@110.
