cam question

[28oz]

okay... while im in the process of doing my valve guide seals, i was wondering.

i heard that the 260Z cam is pretty mild, and there happens to be a whole 260 e88 in my garage. i have an n47 on it now, and i was wondering if i would get any form of gain or performance from putting this cam on my n47 already on the car.

someone told me that a mild cam would go good with the setup that i have, so i was just wondering if it was true. thanks!

aren't all the stock l-series non-turbo cams the same (with the exception of the oil holes)? besides, the e88 cam wouldn't work in the n47 without changing over cam towers

The 260 cam has a tiny bit more duration. Mild improvement is an understatement. There is no point IMO in swapping cams for this 10º or whatever it is more duration. Get an aftermarket cam if you want a cam. At least you'll be able to tell the difference after all that work is done.

Jason is right about the cam towers. Swapping the towers is not hard at all though, so if you really wanted to do it you could.

I know it's not the "right" way to do it but I swapped a cam and towers on an engine without pulling the head. I did drain the coolant and pulled the spark plugs, but I then pulled the towers and swapped them over. Ran that engine in autoxes every month and on the track a number of times in addition to my daily driver miles. It had something like 40K on it when the front crank pulley came apart and that engine came out. My point is that if you're careful you can swap the cam without changing the headgasket.

I agree with all that was said ahead of me . I would just like to add, that when you do a cam change , the rockers and lash pads and the cam that have been running together have worn in a pattern . If you change cams the rockers and lash pads should be replaced with new. Other wise the likely hood of the cam not lasting because of excessive wear is likely due to the mismatch . To go through the time and expence to do this for any used cam is not a wise move if you want my 5c (inflation ) Gary Another thought , the crank in the 260 block is the same stroke as the 280 . And one more thing , if by chance the 260 is an automatic the diff is a lower gear than a manual set up . This will give you a little more at launch, 3.54s vs. 3.36 . Not a huge difference but some .

well.. once i looked at the part where the head bolts go through the towers... i decided to back out. from what i found out, the cam has a bit more duration, but less lift. so torque for horsepower... no thanks there!

if i do it, itll have to be aftermarket... no playing around with parts in the garage for me! thanks guys!
