In my daily playing on ebay, I ran across this rebuild kit from Maddog Racing. Looks to be a decent enough deal to me, what do you guys think. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=7914817824&category=33620
Looks like a pretty good deal. Also check out www.kanter.com You can buy individual components, or complete rebuild kits from them. Buying components individually allows you to "upgrade" to a hotter cam or whatever.
Fastengineparts.com This is the same company, they don't seem to list an adress. Seems a little fishy.
