How does this 360 build sound?

In the car is a 7.25" with 2.76 gears, I bought a SG with 2.93 gears off another forum member and am waiting rto receive to install
In "the deal" with the car I also got all the parts to build an 8.75" (SBP axles though) along with a 741-housed SG with 3.91 gears

Replace the sure grip equiped rear gears in the 8-1/4 with a more suiteable ratio, like the 3.55's and use the XE268H. From there, you could get away with the stock converter though a higher one would launch you much better.

If it is 90% plus street, skip the converter.
