My 86 Berlinetta v-6 was a steal @ $500, and I gutted her, put in a 305 h.o.,holley mech. 7lb fuel pump, carter 500 cfm carb, headers, accel super coil, 440 lift/260 dur cam, blah blah blah. Custom cut driveshaft to fit turbo 350 tranny, and she goes like hell until 70 km/hr, but then no more shifting. I checked the vacuum, every possible thing, but nothing. I can't get a straight answer as to what gears came in a manual trans 86 berlinetta v-6 (2.8 liter)... does anyone know if it's the gear ratio, or is this just some kind of satanic curse? I'm getting pretty annoyed, and would REALLY like to know what to fix. The tranny is good, I have all forward and reverse gears, but the shift timing is just WRONG, so I can only assume it's gears, but want to be sure before I rip everything out again. Thanx for any help u can give.

 

Welcome to the board barbiek9.

This would be a little better suited for out 3rd Gen Tech section. I will move it there for you. If after a while (ie- couple days) you dont get many replies you can come back and try here.

Thanks,
Ken.
