Short duration cams/340

with a short duration camshaft of 210 or 214 at .050in and 8.5:1 compression, what would initial timing be..15 or so?
Wondering how these hi torque RV style cams perform on the street?

If your looking strictly for mileage/efficiency, yes they work well by not bleeding anymore compression off at lower rpms. I think if your looking for some performance, a cam in the 220/[email protected] range with a lsa in the 110/112 range will give you some power over a wider range and decent drivability/mileage. Along with a aggressive timing curve that you'll need also.......And that very well may be from 15* to as much as 20* or a hair more initial, imo. Cylinder pressure and fuel quality will end up dictating your final numbers.
