604 with holley ultra hp carb. 650 cfm stock carb. Msd 6al box and dist. 34deg timing locked out. 6 to 7lbs of fuel pressure. 6.5 power valve and 72 jets front and back. I get ran over on starts. It doesn't bang or miss or anything. Just real lazy. But then takes off like a bat outa hell and runs great. What am I doing wrong or missing with this thing?
