I'd think that cam would be too much for a street engine. I designed a 
more street friendly one with 270 degrees duration (226 at 0.050) and 
0.320 lift. A few guys bought them. Unfortunately, they were done CNC, 
so I never had a master made. I'd gladly share the numbers if someone 
wanted to make one. I think the stock TR4 cams are very good for a 
street motor.
