Tuning larger LT-5 cams - ZR-1 Net Registry Forums

Paul,

Glad someone finds this useful. I'm no tuning guru but I could probably discuss it from the perspective of someone who wants to get involved in their own tuning. The evolution of tools for tuning has been pretty rapid in the last 10 years even for OBD1 stuff thanks to guys like Craig Moates, Mark Mansur, Rob Rauscher and Grumpy. They started out hacking GM stuff and have moved on to Ford, Honda etc.
As a point of clarification, the tuning I have done is on a
stock block LT-5, Fidanza wheel, ported top end and GVD heads w 236d/.425" lift single pattern intake cams & stock exhaust cams. 63mm TB, 1 7/8" Watson headers. Now that Part Throttle is pretty well dialed in, I'm hoping to get to dyno for work on WOT. Results so far show little to no knock retard which tells me top end fueling and timing isn't too far off.
