advance/retard a camshaft

[Nacho-RT74]

does this changes the output HP on your engine ?... I guess of course changes at what RPMs puts out the max HP posible, but changes the max HP lever too ?

if it does... how much affects the max HP output?

[Cooter]

Retard= Upper end HP....Loss of some Low end Torque

Advance= Low end Torque boost....Loss of some upper end power....

Depending on engine specs, this can be as little as 5 HP or as much as 50 HP...

wow... 50 HPs would be A LOT

aaand, I guess affects also the iddle quality, being an advance job ( on a "wild" cam ) make to iddle better

Not to be overly PC, but shouldn't you have said "mentally challenge" a camshaft

Nacho, i advanced the cam on my 400 and noticed a bit snappier down low...top end dosnt matter much on the street and im pretty sure all your car sees is the street.

LOL... just asking to learn... and looking forward with the cam I did choose ( being I use A/C )

The LSA will effect idle quality, installed centerline- not so much.  It will increase cylinder pressure though.
