comp had some roller cams that worked with computor controled pre-magnum engines

i just droped the tbi stuff off of a 91 318 and stuck my lunati voodoo roller cam in it with headers and 4-v on a LD4B intake for my 85 truck

knocking back 18-19 mpgs with the 2.94 gear and has more low end and torque for sure.

if your not wanting to drop tbi leave it alone and add good flowing exhast and run it as it is
