Vale Springs

I am going to be running solid roller cam in the .720 rang just wondering what valve spring most people perfer.I have A429 heads right now they have the comp cam
Valve Springs... 930-16
Ti retainers 732-16
Valve locks 611-16
Lash caps 621-16

I have had good luck with the K Motion springs. Dont know about the Comp stuff.

Those 930-16 spring are a dual spring that have about a 153lbs seat and 383lbs open.
Which look like they are for good hydraulic or flat tappit cam.

If it is a solid roller you will need something better in a double spring but not necessarily a triple.
Your cam card should have a recommended spring spec whether a part number or a seat pressure & open pressure as well as spring heights.

One of the head guru's will be able to be more specific but you also need to be more specific on the actual cam specs if you have them.

Oh sorry I see.

I have ran the Crane doubles(99893), Comp triples(947)
& yet to be ran Manley Nextec's doubles (blue stripe & green stripe).

I hear the K Motion & PSI are also very good.

What valve spring installed height do you have...?

Not sure they are on the truck right now I need to pull them and check everything.The heads was already setup when I bought them and put them on with the comp 930-16

Most likely your heads are set up for a 1.900 or 1.950" installed height. However, you will need to absolutely check them and find out for sure. I understand what Randy is saying, and you really need to do that before this discussion goes any further.

Cam motion is in my home town.they done couple of customs came for me all solid roller
I did have a problem with K800 springs I think? It was on a 362w in a daily driver 83F100 truck I had two broken springs 1 innner broken and the outer one gave me the miss I was feeling. Not that many miles 4K if that. I went to cam motion to get 2 new springs they. Said to replace them all which I did. Bit they where comp cam springs they sold me no problems to date. Personally I wouldn't run cam motion springs again.

Thanks Guys I will post the installed hieght when I pull the heads off just trying to see what brand most like .I am just trying to get all my ducks in a row before I start building this will be my 1st stroker engine.It might take me 2 or 3 more months on this build but I want it right when I hit the track with it so they will be a few more question I will be asking.

Just about ALL brands are wound by the same original people with maybe different finishing techniques.
Each brand has both excellent, good and not so good springs in their offerings so, it is the INDIVIDUAL spring which will fit that application correctly which is most important.

Get it fig out ok?
