is the motor a odd fire or an even fire motor. if I put a high lift cam like 469 lift and the rockers are not adjustable will the lifters will be beyond preload. what size cam will work.
 
I know its probably an even fire motor from what I have researched odd fire motors were only made in 1977-78. I just want to know if you guys that run a 3.8 with any lift, do you need to change the rockers to an adjustable setup
