okay ive got a 383 stroker lt1 with a gm 847 cam with 1.6 ratio roller rockers on stock ported lt1 aluminum heads i need help on what valve springs to get for it.

 

What's the cam card recommend?

 

I'd go with the K Motion K-800 valve springs. They are a very good spring...I ran them on my '97 with a GM847, as have many others. They are good to .700" lift and fit inside the stock seats.

 

What's your budget? Go beehives if you can spend the $$.

Go with the 26918 beehive springs. The retainers, locks and shims will
depend on what you want to do. If you use the stock spring seats then
the 7* hardware will work. If you want to use the Comp spring seats then
the 10* hardware with +.050" locks works the best.

Comp Press Release

If you want to go with 7 degree hardwarde:

787-16 retainers
648-16 locks
stock or LT4 spring seats

If you want to go with 10 degree hardware (super locks):

795-16 steel retainers, or
794-16 titanium retainers
611-16 locks (standard), or
614-16 locks (+.050)
4705-16 spring seats

Using the 7 degree hardware and stock spring seats you
should end up with an installed height close to 1.78". With
10 degree hardware, 4705-16 spring seats, and the +.050
super locks you should see a 1.75" installed height.

Many have used the stock or LT4 spring seats with these
springs. I personally don't like the way the springs sit on the
spring seat. I have the 10 degree setup on mine.

 

ok thanx guys i am goin to go with truedualws6's 10* setup looks like itll cost me a little over 300 bucks... appreciate the help
