Gear Vendors in a '67 Barracuda, is tunnel clearancing required?
but don’t want it to be a slouch off the line.
I have a HO367 with a Commando A833, and a GVod behind it. I have run just about every rear gear from 2.76 to 5.13s, and 3.55s have been in it since about 2005. If I had an automatic , It would be an A999/Loc-up, with a 2800TC and I would for sure try 3.23s This would make the starter gear to be 8.85, a very good street starter for an automatic and a SBM.
With your 727, the starter gear will be 7.91, but your stroker will have considerably more torque at stall than my 367, so it should in no wise be a slouch, off-the-line with 3.23s. And with them, 65=2519 at zero-slip, say up to 2650 on the tach @5% slip, with 28" tires. For a streeter that is pretty good.
The only part I don't like with the 3.23s and a 727, is that 60 mph is around 6800 in first/3800 in second, so some punk with a 4 speed and a 367, geared right, might pzzuoff. So just stay from 4-speeders, and you'll be fine.
The good news is 3.23s are about the right gear to trap the 660 in, hitting about 5750@93/ to 5950@96
