I had a 69 New Yorker beater that i drove for about a year untill i pulled the drivetrain to put in a 67 Coronet, it had 2.76 gears & was bone stock with single exhaust, at 4000 ft. Alt. it would fry the "tire", when i made a trip to 2700 ft. it was a total 'monster", this car had 87000 & a wooped timing chain & point ignition, so if your haveing problems frying those street tires in a B body, something is not right or the tires are VERY good, this may not be a good compareason, but i just put together a 360 magnum with bolt-ons in my 71 dart, it has 2.76 gears, all i can say is trying to "not" fry the tire is a challenge to say the least, i can't even get into the secondaries at 30 MPH without the speedo jumping to 50-55 & a wall of smoke lol.

Exhaust will help but won't net much if you have as tock lo po engine.
It likely could use a new chain and that would make a noticeable difference right there. Did the timing bounce around while you were setting it?
If you want a little more cam, you can switch to a grind closer to HP grind and you can get away w/o changing the convertor. Might free up a little power but won't be all that much.
NEVER run a Fram filter on a BB Mopar. Those are junk on anything but REALLY bad on the BB Mopar as the filter sits horizontal and the Fram lets the oil drain back. Wix is good and you can get them at Napa and CarQuest although they will be labled house brand.
I want my fair share

i just went out today and ran her hard. I moved the timing a little and put some premium gas in her. It flew like a rocket. Smoking tires and all. I also adjusted my kickdown on the tranny. She has woke up! I hit 150mph and the speedo came around to the counter numbers on the speedo. Since I still have the speedo gear from the 2.76 gear I know that reading of 150 mph+ is not accurate. More like 145-150 mph. 
I'd have to guess you didn't break the 120 mark, maybe 110-115 tops, but either way it runs better now & your happy with it, if it feels good, i'd just drop in a new chain/sprockets & call it done internally, just add bolt-ons like a good aluminum intake & a set of headers (if you don't have these), put a good tune on it with good timing curve, in all honesty, it'll respond much better with these things then installing a mild cam & the headaches that go along with it, if you ever do decide to change cams, step it up abit over the HP grind, then get some more gear & a converter that matches, you'll be quite satified.

what gain will it be to add the lifters and chain but no cam? 
I new chain will only fix whatever timing chain stretch (and nylon cam sprocket issues) may be present. Stretch retards the cam.
If I were you I would put a MILD performance cam in there while I was at it.
