dude dont base youre decision on an engine you can use that force 28 till it blows save youre money if youre on a budget buy a mach 28 for 129.00 my buddy has this mill in his msr and it screams. the jammin will suite youre needs for what ever purpose you choose to do with it wether its bashin or racin or both and the aftermarket parts support is starting to come alive real quik. you will LOVE the way the crt handles. but in the long run you really need to buy what YOU think suites you best. good luck.
