Bosh platinums track record

[George M. Dailey]

What about the GM L98 Tuned port engines, do they like Bosh platinums?  I've
got some in my engine now that came with it when it was purchased. And of
course, it always seems there should be just a little more power. I've wrote
it off to my 2.73:1 gear ratio and 27-1/8" diameter P255 60-15's. Does
anyone have the gear ratios for the 700R4 tranny? It seems like my gas
milage in the city has dropped from 13 -14 to 12-13. Dope!
