I have the appointment set up to get my 4.10 gears, T-Lok, Dynotech drive shaft and 255 LPH Walbro pump installed next Thursday. The total cost is going to be around $700 but includes everything like the bearing kit, gear oil and friction modifier. If the weather is good next weekend I will have to take it to the track and get a time slip since it will no longer be a virgin.
