TSP224R or TSP228
#22
Seems like the TR224/224 is the definate choice with stock heads...not reving the motor out to 7,000 RPM's and having more overall horsepower and torque compared to my other options here! Even Comparing the dyno charts between a TR224/224 and a TR230/224 and over the whole dyno graph from 2,200 to 6,500 the TR224 makes more power and torque on average!!!!!
And yes, the TR224 uses a proprietary lobe which is almost as agressive as the Comp XE-R, but at a little less lift.
