That's what I'm asking about... my cam is in 7 degrees advanced. Would changing it to 5 degrees make that much of a difference? Doesn't comp grind most of their newer shelf grinds with 4 degrees built in? Wouldn't the "downsides" be exacerbated on a cam with 25 degrees more duration?
Assuming piston to valve clearance is not an issue.
Thanks for your responses.
Every cam company that I know of puts in 4* and then
MOST still add more... whats the weight of the car,
gear ratio and tire size... this is mostly a street
car correct
