A833 - gearing

The 2.47 low box is a close ratio box and
IMO
Not well suited to a streeter unless it has plenty of low-rpm torque. For a typical SBM streeter it will want 4.10s for a starter gear of 10.13
If yur willing to go there (4.10s) you will be rewarded with a quick trip thru the gears and the engine that uses it can also use a cam with a 108LSA, and the trans will keep her on the pipe..
I have had this combo; 360/2.47/4.30s and it was a lotta fun. But no way on God's green Earth would I run that with a low-compression 318 and 3.55s.
