I remember talking about these truck here before. The article was never posted though.
550hp SAE net, 705 lb/ft torque from 605 cubes of Libgenfelter awesomeness.
Look at that Upper plenum on that intake. Ive never seen that before, and its different than the 7 Chev and 5 GMC LPE 605's that they did. The production models were over 600hp, but were emissions legal.
They all breathed through the dual cat exhaust that was designed for the 1991-93 454 SS that made 255sae net hp/405 lb/ft torque.
Imagine opening up that exhaust would surely up that power.
0-60mph is 4.7 in 2wd and 4.6 in 4wd
0-100mph 12.5 seconds
0-130 in 28.7 secs
5-60 roling 5.0 seconds
1/4 mile 13.3@103
70-0mph brakeing 231ft lol
0.68 g's cornering
Price as tested $68,000.
They get 8 mpg, which is pretty good since teh 1990 454SS with the thm-400 trans and 3.73 gears
were rateda at 9 mpg city and 10 highway and the 91-93 withe thm-4l80e and 4.10 gears was rated at 10mpg city/11 highway. So getting 8 mpg isnt so bad, well at least comparatively.
