So I'm putting together a mod list and looking up the costs of these items..and I've been looking for a Crane 227 Camshaft I keep reading about. I can't seem to find a darn site that offers the Crane 227 for a 93 LT1. So...links would be wicked =)

Crane Cams website - 227 cam specs - click here

If you go to the above link and read down in the descprition you will see that this cam is only for use on Mass Air Flow equipped LT1s, therefore ruling out your Speed Density tuned(no MAF meter) '93. MAF is more flexible when it comes to making changes to a tune where engine modifications warrant. A stock speed density tune just probably can't cope with this valvetrain change, so they don't suggest using it. You could though... would require a new chip for your ECM or a new ECM / MAF combination.
