1980 El Camino, Tremec Magnum 6 speed (T56), Strange S60 rearend with 3.55 gears, will be using Holley LS conversion parts, AED 750 carb, SmartSpark ignition. Goals: fun street car, handles well, daily driveable.

I bought an LS2 package that included a rebuilt short block, 853 heads that need to be rebuilt and a GMPP single plane intake. Considering:

Option 1:

• CNC LS6 heads
• LS2 stock cam or carbureted grind camshaft to be determined, smooth idle
• GMPP single plane intake

Option 2:

• New LS3 heads - concerned about piston to valve clearance and intake valve shrouding
• Carbureted grind camshaft to be determined, smooth idle
• Edelbrock dual plane LS3 intake

- Which option would you choose and why?
- What cam could meet my goals of a smooth idle that will work well with a carburetor?
- Other thoughts?

I appreciate your input. Chris
