88 305 tbi to 350 tbi

What would be the best cam for a throttle body with 350 swap?

I seen this on summit racing. Has anyone tried it before?

I would consider an LSA of 115-116 for puter friendliness....that one is 109... go to their line of computer cams and find one with same lift at .05 but 114 or so LSA

Actually LSA 112 with duration of less than 215 deg @ .050 will work, but it will not be optimum. Anything with longer duration and tighter LSA will result in unstable idle with stock ECM calibration. For a complete novice stay under 208deg and LSA of 112 to 114deg range. A head work, camshaft along with headers (and free flowing exhaust) will be the biggest bang for the buck! Getting VE & SA tables to take advantage of free breathing engine will take you to the next level.
