That's the GM LT4 "HOT" cam kit. .525" lift with 1.6 rockers, duration @ .050 is 218*/228*, LSA is 112*.
Be sure you use the melonized distributor gear (pn 10456413)with the GM roller cam.
You'll need GM's roller lifter conversion kit (pn 12371042), pushrod kit (pn 12371041), and a timing chain kit (pn 12371043), or equivalent parts from a junkyard 350 or 305 roller motor. Go to www.sdpc2000.com
and search out those part numbers for details.
The '93 heads will have to be modified for that much valve lift and possibly for the new valve springs (1.32" diameter). Screw-in rocker studs might also be a good idea.
Check the block to see if it will accept a fuel pump pushrod. Some of the later roller blocks will take a mechanical pump, but not the pushrod that operates it. If not, you'll need an electric pump.
If all this seems too complicated, just send the free cam kit to me.
