So I recently purchased a set of Yella Terra 1.95 ratio full roller rockers for my Grand Prix GTP. These are custom made rockers specifically for the Series II and III 3800 GM engines. They are made in a 1.61, 1.7, 1.8, 1.9, and 1.95 ratio.
They seem to fit amazingly well on on an SC head. The pedastals are a perfect fit, and roller tip placement appears to be good.. I need to head over to a buddys house and test fit them on his spare engine, and roll them through a few cycles and see how everything lines up.
If these work, they would give us .502 lift intake and .515 lift exhaust on a stock 89-93 cam. Possibly a nice bolt-on? Althought, it would require valve spring upgrades.
Anyway, take a look at the pics of one of these rockers bolted down.. Thoughts?
