I picked up today a new camshaft for my project Sigma. It's a mild street cam by Crow Cams and once fitted, together with the twin Solex carburettors and soon to come 2 and 1/4 inch sports exhaust, the old 2 litre Astron engine should be much more lively and fun! This camshaft came at a perfect time since I'm already removing the cylinder head to install a new head-gasket anyway.
Here are the stock camshaft specs:
Valve timing (opens/closes):
Intake=24 deg btdc / 64 deg abdc
Exhaust=59 deg bbdc / 25 deg atdc
Duration: unknown (approx. 268 according to an online calculator)
And here are the Crow Cams mild camshaft specs:
Valve timing (opens/closes):
Intake=18 deg btdc / 54 deg abdc
Exhaust=54 deg bbdc / 18 deg atdc
Duration: 252
