I think I'm starting to figure it out now. I've found a couple of US places who have good experience with A series cams and offer several grinds, both for about $100. www.iskycams.com is one. This page is for the "DATSUN: 4 Cyl. 1300 cc (B-210) & LATE 1200 cc Pushrod Engine (A-12)". That shoudl also work for the A14/15 right? Which of those listed would be best for mild street performance (good drivability etc)? I'm guessing the one listed at the top based on the shorter duration and lower lift.
