I am currently building an 81' for street/drag use. I am installing a 427SB 600+Hp and richmond 6-speed. My question is: how strong are these rear ends? And, or would I be better off with an earlier model unit? Thanks.
For one thing,that 80-82 unit is only good for about 400 hp.There is more upgrades available for the 63-79 set up.As far as putting an earlier (63-79) set up under an 80-82,I wouldn't know what you will run into.But as you have seen by the guys who hang out around this place,anything is possible.I am sure someone can elighten both of us.
My 81 has a Dana/Spicer 44, and it is supposed to be good for large torque handling. That differential mounting frame doubles as a pumpkin cover.
There are many websites that provide information on the Dana 44. However, they tend to be solid Dana 44's (Jeeps, GM CK's, and so on).
There is probably a CAC member that has upwards of 400 Hp or more in their 1980-82 Vette. But I still think that torque is the key parameter when it comes to Dana 44's. (by the way I found a vendor that sells kits for the Vette -----> Reider Racing
