to advance or not to advance cam???

hay moper yes thats the intake a single plane weiand excelerator..as afr as carb go i plan to try 1 my buddy has a 750dp but until then i dont plan to spend 450/500 just to try cause i plan to upgrade things down the road...i tried the m1 before just didnt pull as well but thats when i had the comp cam 306 mag. solid 555/555 in the car.. even cross my mind to reinstall it and try it again. yea the verta is going to have to be changed for sure...lupo says its as far as he can go with it...as far trap rpm i have only been down the 1/8 mile with it last yr. when i got it running,but plan to run the 1/4 mile this yr..but rmp in the 1/8 mile is 5200 crossing the trap.....cam works to 6200 and i shift at 6000 i think the intake works from 1500to6500 not to sure on that....
