I've just finish the build on my 92Z28 and am looking for some help. The engine is as follows:

traditional SBC 383
7730 ECM speed density
Forged Eagle 4340 crank
Forged Eagle H-Beam rods
Wiseco forged pistons
9.5 to 1 CR
Miniram (Like the LT1 intake)
AFR 195 eliminator heads
Custom Cam: 237/247 .560/.580 on a 114 lobe sep. (blower in the future)
1 3/4 headers/ True duals
T56 6-speed conversion
Strange 12 bolt 4.11 gears


I'm looking for a good spark tabble to start with for the 6-speed.

In the past i've used Tunercat,Datamaster and VEMaster(for the VE tables) to tune this vehicle with an auto transmission,but i kind of have no idea where to start with the spark table for the 6-speed.

On rough start-up it looks like it will idle around 950-1000 with an idle KPA of around 60-65

If someone with a similar cam and 6-speed could post there spark tables i would appreciate it. I don't have the Tunercat def. files fo the LT1, so if you could post a pic or text of the table that would be appreciated.

Thanks
