Additions:
--->**GM part #24570698 or #22545390** (a little confusion there)($197.64). The cam casting numbers are 255/455 (which IS the same number as the HO cams, but only has 0.3750" of lift, not 0.410") and the housing/carrier itself is 22542963.
**The swap includes: (note, turn engine 90 degrees odd TDC, so all the pistons are down, and risk of damaging a valve is out)**
- remove plastic shiels to gain access to the passenger bottom of engine
- support lower passenger side with a jack
- remove upper motor mount
- move coolant resivour (unhooked 2 lines)
- remove belt
- pull the crank pulley off (puller)
- remove the side cover (20-25 10mm bolts and 3 nuts)
- remove chain and exhaust timing gear
- unbold the whole side cover from the block (13-15 bolts 10,13mm)
- remove IDI cover (unhook ignition plug)
- remove the top 10 bolts on the cam housing carrier
- replace cam
- reverse process (with the exception of resetting the chain tensioner and you need to time the engine)
===Tools Needed:===
- pliers
- jack
- 3/8" ratchet and 6" extension
- 10,13,15mm sockets (I prefer deep when I get to the chain tensioner and the tensioner pivot)
- 15mm wrench to reinstall belt
- pulley puller

24575256($12.23) _ Guide. Same as above.
992704($NA) - Assembly Lube. Good idea to coat the cam lobes and the carriers where the cam contacts with this stuff.
