Thanks for your advice! Yeah I've been reading and researching since posting the thread and all indications agree with you that the right 8 3/4 should easily handle the horsepower range I'm working in. Also seems like the 3.23 gearing will better suit my needs as I love driving on the freeway without a high revving engine. I'm slowly checking off all the different parts that will best work for my needs. I've also been considering a different transmission with overdrive to help get the best of all worlds. So far the only way it looks possible with a 904 tranny is by spending a fortune on gear vendors overdrive unit..... I'm sure there's cheaper options? Thanks again!
