New update.

After I swapped in the new motor I have driven it for about 150 miles now. It has plenty of power for normal driving, and doesn't feel stretched to accelerate the truck. Even with a engine in back. Also I know have a 1800 rpm stall converter vs the old 2500 version.

Old motor 10-1 gen2 LT1 with a Corvette cam, 1.6 roller rockers, and 1992 vintage AFR 195 heads. That I believe are the cnc version.

New motor. 10-1 gen2 LT1 with a B-body cam, factory steel 1.5 rockers, and factory aluminum heads. This was a Caprice engine I got with a carb intake for a price I could not pass up. So all I did was regasket the engine, and use the factory aluminum heads instead of B body iron heads. For safety with california gas as I run a quadrajet. Honestly I believe below 3000 rpm at part throttle to accelerate. This engine puts out atleast 25lbft more torque below 2500 rpm. After that it just doesn't carry, but who cares. This is a driver for my dad.

So if your building a similar truck and engine. 3.08's are fine if you want a driver or minor work horse.
