The SC-100 is the unit for the small block mopar. however, you need to buy the adapter plate (SC-146).

Between the two parts, you are at: $205.99 + $59.99 = $265.98. To use it, remove the rocker shaft assembly and bolt it to where the shaft assembly would normally bolt to. Then use the tool on one section of I/E at a time to compress the springs. The good thing about it, you can compress the spring and use both hands to install the retainer and locks.


This is cheaper, but may be more difficult to use with one hand while I use my other hand to install the retainer and locks.
