Thought you guys might like to see a pretty kick *** little 5.3 on pump gas that got tuned yesterday. Combo is a 2001 5.3 with 862 heads, LJMS stage 2 cam, Forced inductions Billet S480 with a 92/1.10 hotside through a TH400. Tune is 18 psi/11.0 afr/ 11 degrees of timing with 91 octane pump gas and windshield washer fluid in the meth tank. 750.92 rwhp and 711 rwtq. One of the few pumpgas tuned 5.3's I've seen make over 700 rwtq. Kudos to Kris Kardimos out of Reno NV on the tuneup...

granted, the turbo was more expensive but i wanted more than an "off the shelf" cookie cutter all out race turbo. i wanted to drive it on the street with reasonable spool. could i have cut the cost in half and bought the cast 80mm wheel and the standard 96mm turbine? hell yes! and the power would be about that same at this level. i paid more for some things that i thought would be important to me ON THE STREET. was there some lessons learned along the way? hell yes! you cant push these motors beyond 15 psi with stock head gaskets and head bolts! but a few hours in the garage over a weekend fixes that **** and its a moot point! i plan on working with liljohn and my tuner to push this motor as far as it will go on the stock internals. if it blows a motor big deal. ill either buy another $500 motor or forge one and go from there. either way im just happy to be a part of this process.

John nice job. Yes Del and I are not in the inner circle anymore over at chevelles but that's Ok. BBC's are a great engine but they tend to be horizontal milling machines because of bad cams or lifter failure.
