Any suggestions for engine and transmission rebuild kits? So far for the engine, I'm looking at this kit. Budget Priced Engine Rebuild Kits from RPM Machine

Transmissions is Master Rebuild Kit, 700R4 4L60E AOD 4R70W

I'm thinking about upgrading the cam, doing some head work and port and polishing and maybe bore it during the rebuild. Nothing crazy but alittle more power would be nice. I need the transmission to be able to hold the extra power. Thanks!
