Re: 1986 block, 1987 heads- CAM HELP
No reason the TBI cam won't work with a carb. But as mentioned above, it's quite small with an emphasis on low RPM torque. Something like a Summit Racing SUM-K1101 cam & kit would be an improvement, without killing low RPM performance.
https://www.summitracing.com/parts/sum-k1101 Be sure to read everything you can on breaking in a flat tappet cam! As moderate as it is, a 204/214 cam would be a bit big in a 305 with tall gears, like 2.56 or 2.73. Edit: Yes, if you install a new cam, you must use new lifters and probably will need a new timing set.
