I have a 1966 El Camino with a 327 engine coupled to turbo 400. The engine has a mild cam 202 double hump heads, edelbrock performer rpm manifold, edelbrock perform 600cfm 4 bbl carb and headman headers. I need help with the following questions;
- Does anyone know what the timing should be set at on this?
- Do the 202 heads require a lead additive to the fuel
- What gap should be used on the spark plugs.
- Carb is brand new, however when placed in gear the idle drops significantly almost to a stall. Idle when in park is about 950-1000rpm. Fuel pressure is at 5psi. Any ideas?
