1978 K20 454 Swap

Hey looking for someone who has experience with a 454 swap on a K20.

My truck currently has an 8 lug GM 10 Bolt front axle and stops great with the little 350 in it, but I am worried that the front brakes and ball joints aren't going to hold up and perform well with the additional weight of the big block engine.

Also I have driven some diesel trucks that just don't seem to stop for **** and I don't want to experience that with this swap.

Is a front Dana 60 king pin axle ( CUCV style ) worth the money for the increased capacity and how much will I gain in the way of brakes ? They are also getting hard to find. Any info on this would be much appreciated. Thanks
