We have never run our Racetech out the back door as my son is only allowed to go 7.50. We run it with 10 degrees of timing out of it and a small 1050 carb most all the time. The only time we ran it all out was in Salt Lake las year and he went 7.53 in 9200' DA. You don't NEED a ton of camshaft in a light dragster to get after it. We went 8.teens with a 446 in the same car here in Vegas with an OOTB -1 head and tiny roller on pump swill.
