Re: Street feel of the Dev 5 / 5a ???
JMM cams are really good and deliver the outputs they claim closely enough but if you truly want power in the 2000-3000rpm range you waon't get anything better than an XR6 cam.
As soon as the BBM switches the JMM cams really deliver but below that they just match a stocker.
Best choice is go the JMM and drop a diff ratio to make up the low end difference.
