so my savage... running the F 4.6, (tried my SH .26 too) is running a 17CB and a 47 spur. dynamite maxlife shoes with 1.1mm springs. both engines labor a lot, and my brand new maxlifes need de burred at 8 tanks. the truck itself has a gallon on it. FLM extended, running the stock jelly donut tires. i have a NIP 2 speed i kept as a spare, so i could replace the trans if need be. the truck is not stuck in 2nd gear, it does shift. any ideas?
