HP / Torque estimates Ok here's what I am putting in the truck over the next few weeks. Just took out the old 5.3 today. It has been a long time (last time I did anything like this to a car the 350 had a distributor and carbs). So not sure what to think on the outcome.
6.0 bored and stroked to 408
317 heads with full port and polish
Ferra stainless valves intake enlarged to 2.02 and exhaust enlarged to 1.57
Valves were match ground to the heads - vacum tested each and hold vacum for 30 seconds
Upgraded valve springs
New GM rockers with trunion upgrade
Cam - .588 / .598 115 degrees separation 277/283 duration
Double roller timing chain set
Upgraded oil pump
TBSS intake and TB (intake matched to gasket and mild porting done, TB is ported and polished)
80 lb injectors (holds 60 lbs fuel pressure at WOT)
Forged aluminium pistons with -15 cc dish - compression calculated at 9.4:1
Rings set up for boost
ATI damper
Forged Callies crank
Forged Manley Hbeam rods
Flowmaster shortie headers and 3 inch pipe through dual series 40 flowmasters
Procharger D1SC with pulley to pump 12 lbs at 6000 rpm
4L60E with "Beast" pack, kevlar bands and a few other minor upgrades
Hoping for 750 hp at the wheel and 650 ftlbs. Think I will make it?
