I have an 83 gt with a .060 bored over 302. lunati voodoo cam lun-61000 with gt 40 3 bar heads, wieland intake and 650 carb. I used my 1.6 rockers for the time being but i have heard both i can just bolt on the 1.7 and you cant. Will the cobra rocker arms work with my set up and would gains be worth more work. I run a tremec t-5 2.95 and detroit locker with 3.73 if that matters. Thanks in advance.
