If you want to go faster then the cam you have got now seems to me needs more converter to put you in the power range. You lost 60 ft ,but your cam range is higher on bottom end (2500 compared to3500) .If you put a looser converter in, it should pick your 60 ft up in turn you should have more et. Cam must be good to run same mph and worst 60ft. Just my opinion. I have gained a lot of et in just converter testing and still testing. A 283 may be more sensitive to converter playing than a larger cubic inch motor is. I had 3 tenths change in just converter swapping so far.
