Looking for 602 w/ 4bbl DYNO SHEETS

Anyone have any? Two big tracks here in New England are allowing 602 and 603 crates to compete against big open motors up north but will not allow 4bbl carbs. They are making everyone stick with the 390 2bbl. A couple guys tried it at the season finales and just got left behind and the tracks see no problem with this. Trying to fight a battle for the little guys... Would appreciate any help! They are completely pricing the little budget racers out of racing up here with these big open motors. Only the 603s are relatively close...

Don't know about any dyno sheets but GM claims 350 HP @ 5000 RPM and 390 ft lbs of torque @ 3800 RPM with the 602 w the Holley 80541 650 cfm 4 bbl and 1 5/8 to 1 3/4 Street Stock (under chassis) type headers. What tracks are doing this and with what classes?
