The Best V8 Stories One Small Block at Time
1) New set of valve stem seals (GM part numbers 12533586 and 12457652 for intake and exhaust respectively... $12.08 and $11.12 respectively from www.gmpartsdirect.com)
2) LS2 timing chain (GM part number 12586482... $27.75 from www.gmpartsdirect.com).
3) Either a new front cover gasket or RTV. I would just use oil resistant RTV, but the gasket is GM part number 12574294 and costs $13.33 from www.gmpartsdirect.com.
4) New crank bolt. The GM bolt is part number 12557840 and is $2.62 at www.gmpartsdirect.com. The ARP bolt is part number 234-2503 and is $27.99 from www.texas-speed.com.
5) Crank pulley puller tool. You can rent one from AutoZone.
6) Crank pulley install tool. This will prevent you from stripping the threads out of the front of the crank. A member here, 618Hawk, made the one I use, and it is absolutely worth the money. Look at this link for details and pics.
7) New cam gear bolts, preferably ARP. Mine backed out on me, so I'll be replacing them every time I have to take them out from this day forward. The ARP part number is 134-1003 and costs $6.29 from www.thunderracing.com. I can't seem to find the GM part number, but they're cheap.
8) A couple dowels of some sort to hold up the lifters. According to my research, you want 5/16", and you should get metal dowel. Wood is probably a bad idea. If you don't want to fool with it, you can get the JRP cam install tool from Thunder Racing, but I'd avoid it personally. It's $84.99 if that's the route you decide to go.
9) Red Loc-Tite.
10) A spring compressor. The one from Crane Cams is absolutely unbeatable, but it's expensive. The part number is 99472-1 and costs $114.99 from www.thunderracing.com.
11) Be sure you have a pen magnet. It will be a real help when you're trying to pull the locks out.
12) Some thick motor oil (I use straight 50 weight) or engine assembly lube for the new cam.
Anyone see anything I missed?
Gauge's list is awesome though!
