Is this a good setup for street/haulin' butt?
So you think a 3.55 rear would help out a bunch in this equation, then?
I will be driving from Idaho to Oklahoma with it first off, n then out to shows eventually, occasionally, but mostly around town...
I run 3.55s with a 367 cuber and a 276/286/110 cam.
This is a poor combo for the highway. and
Not the best I've had for around town either. But with a 3.09 low, the starter gear is 10.97, and 5000rpm,where the power starts,is 37mph. And that is really big fun. The .78 GearVendor O/D brings the Rs down to 2200ish at 65mph. And that is also great!
What's not great is the 276* cam that is pretty hard on fuel. But since the car is no longer my DD, I'm leaving it in there. My previous cam was a 270/110&
[email protected]. This puppy was waaaaaay more fuel-friendly.I think the 3.58 stroke had something to do with that. The smaller cam also had quite a bit more off-the-line grunt. But it was done a bit earlier too. For such a small difference in sizing (6*intake) It made a huge difference. I really liked that smaller cam.
The difference from 3.55s to 3.23s is 10%. That's 10% more grunt off the line, and 10% more rpm on the hiway.The engine will run up the tach a bit quicker too. But with your 2800TC I'd leave the 3.23s in, at least for a while.
-Personally, in a lightweight 70Dart, I'd probably go with a a little less cam, if the room was there in the Dcr. Two sizes down would make so much torque,you will have to tub it to put some decent tires on it. And the 3.23s will be perfect. Peak torque might be around 40mph in first, which means when you punch it at 40, and the tranny goes into first,she will light up pretty much any tire you can fit into the stock tubs, and more. Those 3.23s will get you 2600@65mph. With a cam one or two sizes smaller, the fuel consumption will go down, and that put's money back into your pocket. But if there is no room in the Dcr, having to run premium takes the money back out.
