Your best option would be to build a stroker short block (I'd say 512) and use your current 440 source heads. The stock 440 source heads would be a choke point but I think would be the cheapest way to get into the 10s. If you have extra coin to spend upgrade to the TF 240 or the 270 depending on which route you want to go. My car weighs 3120 with me. I ran 10.80-10.90s with 440, stealth heads, 590 cam, 750 carb, speed pro flat tops (mid 10s:1 compression). I have since switched to a 440 with ross pistons 10.9:1, 557 cam, 850 carb and TF 240s. Typically the car runs 10.60-10.70s, been a best of 10.49. Tried TTI 1 3/4" and now using Hooker 2" fenderwell headers with a 6" muffler. Went from a Weiand single plane intake to a Victor 440 and didn't notice much gain there either. I shift at 6000 and try to cross the strip around 6200-6300. I just don't think your going to get low 10s with a stock stroke 440 with that low of compression in that heavy of a car.
