Isn't the 741 the rear that came in the 340 ABodies from the factory?
No problem at all, I abuse them all summer long, and so do lots of others.How strong do you guys think the 741 is? Handle mild 440 easy enough?
Yes Mark, It's OK. That case works fine for what you are planning.
I'll happily take all those junk, weak sauce 741's with the equally junk cone sure grips since they are worthless... LOL
Each of the cases have a weak point in original pinion design.
Unless you are dead hooking a big HP car that weighs a bunch, any 8.75 rear is good. And when you get to that point, there isn't a 8.75 that will live in that environment for long.
