You really haven't given alot of info to make a real choice or to be of real help,but given that as a sign that your building a street car you'll want all the low end torque you possibly can get. A 440 would be great but unless it makes a solid 80hp over the smallblock it won't be quicker. 4"stroke small block would be easy and fun for a mild street car. Quench is about 20th on the list of performance gaining tricks it's just not something to worry with. I've built small and big blocks with and without quench and it's near the bottom of the list. Just a WAG from your info,build a 4" crank 360 with any heads(except 302's) you can afford 280X.500" hyd cam,compression 9.5to1 ish ,headers,2 plane intake holley 650dp and go have fun.3000 converter and 3.91 gears would be good but again you can get by with less.
