Want to change can in my 360. Looking for some advice as to which direction to go. 260 to 268 duration @.50 seems to be the average response I get. Getting many options but all seem to big in my opinion. Also looking for some help getting the car to hook up. Have 800&900 springs in front and 200&150 in rear. The car is good in but just can't get back to the gas with out buzzing the tires. Any advise would be greatly appreciated. Thanks
