Kilowatt, i am sold on the cam advance mod, when i do the valves it will be done! Easy and free, how does it get better than that!
Please share the results you notice, when you complete the mod.
Fun fact: One camshaft sprocket tooth subtends 7.5 degrees, corresponding to 15 crankshaft degrees.
Whimsical thought; valve timing has been altered to achieve, "additional free power." Has no one altered the IGNITION timing for that effect? At least, the ignition could be advanced to take advantage of higher-octane fuel, for proven extra power.
More sophisticated electronic ignition timing "mapping" might yield even greater performance.
The as-built ignition timing curve remains unchanged and inalterable; adjustable timing might have promise.
Then again, the prospect of raising compression ratio for higher performance and fuel economy remains with us . . . might be FREE (as in, remove jug base gasket, replace with compound)! Shaving the head, say, .030", wouldn't cost a lot at a machine shop; resulting valve timing change should be insignificant.
Just a couple of known and proven approaches (ignition timing advance, raising compression ratio) to engine hop-up.
