Trae,

I'd try 3.42s. Assuming a tight convertor, 27" tires, and a 100 to 105 trap speed, you'll be *around* 4800 through the lights. Even if the engine runs out of steam prior to that, imo, it'd probably still et better than with taller gears.

If the cam is stock, it'll run out of steam at 4400 or so, so I might try 3.23s, but no taller, if 1/4 times are your biggest concern.

Fyi - assuming you have a 7.5" rear [I'll say a prayer for it], you'll need to change carriers, or run a spacer to run 3.23s or deeper with your current carrier. You could run 3.08s with your carrier, and although they'd be a big help vs 2.41s, but 3.23s or 3.42s would be better imo.

Fyi - I have good used 7.5" 3.23s, 3.42s and 3.73s for sale. $60 shipped for any set. I'm looking for 4.11s for a 7.5", btw, anyone has a set.
