If I have to ask about a 8 3/4 Im not going to be very confident. better off with a 60 or a 9" ford in my oppenion.

Going on 8+ years all in the 10`s at 3200lbs. and I run the 742 case w/Richmond 4.11 gears, Dutchman 30 spline axles, stock caps and a backbrace.
LUCKY...Is correct word in this post.
The time is going to come when all of you 10 second cars hook up 1 good time and the weak link is going to cause you to spend lots of to fix you Trans/rear/and maybe the motor.
You all need one of these...
I've been in the 8s with my 8 3/4... like I've said a thousand times "I think its a weight issue"... JMO

I ran a string of 10.70's on my 8 3/4 this year. Stock axles, stock caps stock gears and a stock cone sure grip. The car is 3400 race weight with exhaust on. HOWEVER I have a big squishy converter, and I think the 3.23 gears are saving the axles. Best 60' was a 1.55 buy most were 1.59-1.61. I plan on changing to a Dana 60 this winter. Here is a video of a 1.61 leave. It doesn't look like this set up will break anytime soon, but it's a boring launch. http://www.youtube.com/watch?v=8-PO1bCE3E0&feature=youtube_gdata_player-Kenny

In may I was down to eight cars and the chick I was racing went red. I had a 5.99 dial in on it when the 8&3/4 let go. It broke the trans too. So I stuck a Dana in it, now I can tranzbreaking it every pass and not worry
The last street gear I had broke the teeth on the ring gear on the final points night with 4 rounds to go. I needed one more round to win the track championship. That thing made it through 4 more passes and not only did I win the championship but I won the race too. When I pulled it apart the next day I was amazed it lasted the rest of the night. It looked like it shouldn't have made it onto the trailer.

I think if you sit down with a piece of paper and cost out making the 8 3/4 stronger vs installing a Dana, you will have your answer. Either way get some good axles in that thing. BTW congrats on your promotion!
