So does that mean you recommend this one and if yours blows that you would just build another 8 3/4?
starting from scratch I found the two to be a wash. One not any more expensive than the other. Pretty much everything being the same it cost just as much to get the ends and buy the Dana and get it shortened as it does for the housing of 8 and 3/4 and the 489 or the other two. The axles bearings gears spool or trac-lok pretty much the same price.
To the op-
People will tell you about the ease of being able to swap the gears with an 8 3/4 but seriously how often does that happen? If you're at that level of drag racing you're not asking about it here.
