Why Carb and non OD a Gen 3?

[Muad'Dib15]

Ouch.

For what it's worth, with the double OD wide ratio T56 Magnum, 3.73 gears and 26.7" diameter tires, I calculate 1528@65 mph. If I end up running a square 275/35R18 setup instead, I will probably drop down to 3.55 gears which works out to 1516@65. Both are around 1750@75.

I would worry that this will lug the motor, but my 2015 R/T cruised at 1485@65, so not worried at all.



I was daydreaming about one of those just today. It would be a tough call for me to have to pick between most any E-Body and a 71-72 B-Body.



I'd have to go back and watch it again, but I think the Reignited guy put the same cam in his 6.4 swapped C10.

I know I am limiting myself, but really want to keep the VVT and the 6.4 cam in a 5.7 is supposed to be a really nice combo. And seeing my cruise RPM's, just seems like the best bet to keep it. I understand though and really expect that once I have the car driving for awhile I will want more. But at that point I can either swap in a 6.4, or bolt on an HC blower.

My G8 had a 2.92 rear end and a 6l80 od trans. At 70 mph it cruised at 1750 so that's right on the money. I wouldn't worry about lugging the engine at that rpm even if you're going faster.

No reason to really go gen 3, if you don't take advantage of all the tech.

I'm aware this is an older post, I thought I'd throw in my 2 cents.

Better and stronger block
Better lifter angle
Dry intake manifold
Better sealing
Heads that outflow top shelf big block stuff.
Stock valve train good to .650 lift and 7500 rpm
All available at your local dealer
Less cost than the high end LA or big block parts.

Just a few advantages I see, not starting an argument.
