What do you think of my odd combo? LQ4 6.0L, stock pistons
PRC Stage 2.5 5.3L heads 60cc chambers
.045 Gasket
Howards 226/232, .578/.587 cam, 115 LSA
SLP 1.85 rockers (.629/.638 lift on cam)
Stock LQ4 truck intake, TB and MAF (wish I had the money to change this!)
Pacesetter headers
3" x-pipe, Jones maxflow mufflers, turned out infront of rear tires
This is through a 3,000rpm stalled 4L80e, 4.30 gear 8.5" 10-bolt
Car hasn't seen the dyno yet but has been street tuned using a wideband and HP tuners and seems to pull really hard.
Any input on my timing curve? My research has given me a lot of widely varying information. Right now it's 24 degrees from 2,000 to 4,400...drops to 22 degrees at 4,400, then ramps up to 26 degrees by 6,000 to 7,000rpm.
