calming the car down on the starting line

last years runs were low 50's high 40's. Timing was only change. I made the change before the last run I tried to make last fall. Haven't made a clean pass since the change. But also have only had the chance to get it to the track once since then either. I'm still on a carb, so jetting is about all the fuel tuning I can do right now. My hilborn setup is at spuds place as we speak. I think the 5.0-4.90 expectation is pretty close for the topend I have right now. The heads are only flowing just over 400 at 700 lift. Too small for this motor I think. I wasn't planning on going this big, but a great deal on a high dollar crankshaft came along right after I had bought the new block, so here I am. The heads and cam were off the old 526 that the block died on before ever getting a full pass

What air pressure in slicks?

After reading your OP i realized not answered question. I would do weight bar first. I have noticed most guys have added weight to front to make car work.Although sacreligious  to add weight its faster than sideways and /or lifting off throttle. Also cheaper than gear swap and easier to change if need.

crider:
Hemi Dakota, I had 7.5 lbs in them. I would have tried adding a pound or 2 but had forgot the air tank at home

PSweeney:
I think theres 3 aspects.  Weight, tire pressure and the bar height.  Get the nose weight and tyre pressures balanced so it doesn't dead hook and you get some wheel speed so it reduces the shock load on the bar / tires, then set the bar to just above the tire squat height, about 2" assuming the weight/tire pressure ratio is right.
