my 5.3L calculated with my ET/mph to 640HP car weighs 3660 w/ me in it, and 10.30 @ 131mph, I cant build a lot of boost off the line and it dont hit full boost till after the 60ft, im also blowing through my converter higher RPMs than I should going through the traps at 7500.. 3.50 gears w/ 29.5" tall tires. So im sure it makes more HP than it calculates out to.
Stock 5.3L shortblock (junkyard.. mileage unknown)
15psi boost
50hp shot of nitrous.
Living strong going on 3 years.
