the only difference in the 305 vs 350 tpis is the injector size 305=19lb hr and 350=21lb hr the plenum and runners are identical,corvette was only slightly different the fuel inlet and return are on the right side of the fuel rail while all others were on the left side. in my first post i forgot to mention the BBK 58mm throttle body for added air flow also.as for the best unit for intended purposes the 82-86 were mass air flow sensing and are more forgivable on engine mods,cams,heads,and displacement the 87-92 were speed density using a map sensor and are pretty picky about ANY mods to the engine...hope this helps
