cam selection

I'd stick with your 1.7s & get the B-303. I really don't think that the rocker/guide plate wear would be significantly worse. I wouldn't shell out the extra $$ for 1.6s. I know many stang owners running the B cam w/ 1.7s and have had no problems, even after 50,000 miles. My motor has ran like a champ since the rebuild...but then again I only have about 18,000 on the new motor and haven't checked for any where.
