Dave my time before my new heads was 103 @14.3. With 30 more hp and torque and a stroke engine I should be able to get in the low 13's with a 3,000lb. truck. Don't plan on racing it much, just a few times this summer as I spend most of my time crusing. A good friend of mine and I are building a 60 chevy Impalla with a 454 engine putting out 580 HP(estimate). Both of us are a little short of money so it's going to take awhile. He's got the shop and I have the welding equipment and Plasma cutter and tools, but were both retired and living on a fixed income so we do what we can when extra money comes in.
