We sell and install many Tman 555
The 555tq is a nice pulling cam I call it truck cam for pulling. It pulls real nice up to 3800 rpm tq right there. It likes stock 9.3 or 10.1 max for compression.
The 555 Std is a nice over all cam pulls real nice all the way up and you can run 9.5 to 10.8 comp and it loves up.
My self and Red Rock HD have seen this cam make on 103" and 107" 116 hp and 120/128 tq.
But the TQ one does make more down low power faster than the std 555 but the std makes more mid and top end and carrys the tq curve longer across the rpm range.
Either one you pick you will enjoy....
One of are dealers thats (Tom at Deklab Equipment in Sycamore ILL).Sells are products bought a 525 tman and Dragula 2:1 with pvc and tuned at Workmans HD on a 09 96 inch motor made 93hp 103 tq.

Not bad for a little cam..
And the 525 and 555 std are the same but the lift is a little more on the 555.
Any questions TR or myself would be more than happy to help.
Thanks
FD.
