, the gearcase will hold you back, it wasn't designed for speed, very blunt in the front. Normally, I wouldn't tell you to put a nosecone on it till you were over 75mph, but on that old case I would do it anyway, no need to change it, just reshape it.... The post 79' gearcases were much better and I have run them close to 80 with out a cone but that was pushing it. The 135 should get you into the high 60's or 70's, it has a taller gear ratio than the later V4's, find yourself a 14X22 Chopper and have it rehubbed and go from there.
Don't be afraid to spin it over 6K we ran them there all the time.
