5.3 cam question vinci ultra torque
 

Looking at a Vinci ultra torque cam for my 5.3. Anyone tried these? Can I run stock valve springs?

LIFT .551/.551
LSA 116*

no on the valve springs.

Re: 5.3 cam question vinci ultra torque
 

ls6 springs are cheap and should work fine with this cam. I would make that swap at a minimum.

X2. Although I would also replace my pushrods since you are there.

For that price you can get a custom cam ground. Any reason you want that one specifically?

good point I did replace mine with harden pushrods when I did the cam swap.

Not dead set on using Vinci. Just looking for a mild cam that will give me a little sound/ torque over stock and keep my fuel mileage

go over to ls1tech in the used section and pickup a takeout z06 cam and ls6 springs. easy cheap power, under $250 and very driveable

I just got the vinci trucker cam, i havent installed it yet. Im taking out the z06 cam and probably the ls6 springs.
