@DON has Yella Tera rockers on one of his engines. Maybe he can give you some insight.UJpdate. Short block is fully assembled. Pistons are reinstalled, lifters have been changed for 302 oil though design lifters to acomidated the yellow terra 1.65 rockers. Oil passage for the head is blocked off. The head is now wearing a matching shade of blue to the engine. Just waiting on my throttles to return and then i can start mock up with them. Does anybody have a starting point in pushrod length for a 200 with the yellow terra rockers? I'll need to measure for new push rods.
