OK, so since i am going nutz and building up a 402 that will probably make 650+RWHP I figure i needed to ask some questions about the drive train... Here is what i have, anything that will need to be changed out to take the power?

- Stage-4 4L80E (No problem here, rated for 850+ at the crank)
- Stage-4 1,600rpm stall TC (No problem here, rated for 1,000HP)
- Stock 1500 truck Transfercase (Issue?)
- Stock Shortend Driveshaft (Issue?)
- 4.56 gears (should be fine)
- Eaton Posi (I really hope this will hold up since i just got it one month ago)
- Oh and 33x13.50R18 All Terrain Tires (Traction will not be a problem )

Thanks

 

1.80e with hd2 kit,4quart pan and big trans cooler
2.you will want more stall then that even with those gears"it will help with any lag"
3.i think parish8 stock T-case was good for 800 rwhp.
4.Give chuck at finish line transmissions. he helped setup parish8 z71 that has over 1000rhp and1000ftlbs. ps he is a great guy very helpful.
