• Hyd. Roller
• Valve Lift Int/Ext. 0.553/0.578
• Valve Lash Hot Int/Ext. 0.000
• ADV Duration Int/Ext. 275/284
• 0.050 Duration Int/Ext. 228/238
• Lobe Center 112

I am waiting for the Holley HP ECU part #555-604N equipped with an NTK O2 sensor and I have NO engine dyno near me. I am so scared of burning up this engine by doing something carless from lack of knowledge. It is also an N/A engine. I had the new Dry tail risers by EMI made with a bung in each side so I can have one for Holley and one for a dash mounted Wide band.

I have no clue what timing to run on a Big block I'm more in tune with an LS and what heat range plug to start with???

And for knock sensors, do these blocks even have provisions for that? Mine is a brand new GM performance 502 block as my stock one cracked in a water jacket.

They do not as far as I know.
