my pt88 5.3 truck Here's a lil vid of my truck, It's a stock bottom end 5.3, ported 862 heads, small 224 cam 20psi 
4l80e. Truck weights 4k and best time is 10.01@135 on drag radials. First race in streets of mexico is vs a heads and cam nitrous ls2 on 60 roll. Second race im not sure on the times of the camaro but owner said it traps 145 in the 1/4 and his best mph is 150(this one was a 30 roll) I have given hell to this 5.3

I need to know this as well. A friend of mine has a mint 05 5.3 with 39k on the clock and would love to trade plus cash for my 370 Speedinc built short block. I like the sound of building a cheap 5.3 vs possibly blowing up my built motor chasing that magic 1k rwhp. I just need to know which years to look for and which years to stay away from. Thanks

It has the heavy rods, a friend gave me the short block and i slapped some 862s i had laying around. Depending what i set the 2 step i can leave at 4k and have full boost instantly as soon as i let go. Im running dual walbro on pump e85

Transmission had the clutches upgraded, transgo and transbrake but thats about it. Right now i have the tranny off im planning on upgrading to some billet parts. Im planing to go with a lsx and large frame turbo later this yr. Timing under full boost is 14*
