Im running 272's with around 10.5mm lift on a 2.5L. Idle had to be increased to 1000rpm to get it stable, allthough i have no idle motor anymore which doesnt help. Never had any stalling problems.Torque till 3500rpm isnt great but i rarely go below 3000 anyway so it isnt really an issue. The trade off is that they really come alive up top, 10.9 at 132mph on pump fuel with 24 psi from a relativly small GT3040 proves it.
Theres a good discussion on camshafts happening on supra forums, interesting read to say the least http://www.supraforums.com/forum/sho...9&page=1&pp=25
