Stock Bottom & Boost - Reliability List
My stock block with 317s and a cam held up to 733hp, a daily basis *** beating and 2 over heats with 0 signs of damage or concern. Only reason for upgrading is because I have nothing to do over the winter and I want to run 20psi.

MP1900 Maggie @10 pounds on an L76 converted to non DoD, 221/226 cam, GMPP LS3 ported heads with more porting. Stock Converter. Etc, etc. installed at 20,000. Now at 32,000. My tune makes 601/588. Never broken once. Runs an 11.3 with street tires and its just my everyday DD that gets my fat *** to school and back.
Stock LQ4, Custom Cam, Stock Heads, ARP Head studs and Rod Bolts, Precision 76mm, Through 4L80E:
11.5 LBS = 655 RWHP Pump and Torco Mix
8.5 LBS = 585 RWHP Pump Only
Sees 6800 RPM on the REGULAR
Been together for roughly 6k miles total about 4k of which were at 550 RWHP then the last 2k have been somewhere in the upper 500 range. Motor had approx 60k on it when I installed it and boosted it.

Gt45r-18psi-762whp-130k-156k and still going strong.. Now I've had it nitrous, procharged, automatic 4l80e, and now its 6 speed t56, and the only problems I have ever had was tranny, drive shaft, and rear end.. And a few head gaskets. But I've had a variety of built heads on this block and different manifolds, and I built my turbo kit
