Valve Spring Questions
 

Alright, here is the cam that I have:

Duration Lift w/ 1.6 rr LSA

218 0.528 0.537 112

I was wondering what spring I should use, I have been thinking about the following options:

Crane cams 10308 kit with 99893 dual springs

Comp cams 983-16 springs with stock retainers/locks

Comp cams 26918 springs with stock retainers/locks

Any opinions are welcomed. I am looking to use as many stock parts as possible, such as the retainers and locks (not sure if possible) and I was also hoping to spend as little cash as possible! (haha, not gonna happen). I do not want to cut the spring pockets....

Thanks for your help,
Ryan

The cam manufacturer is the best source for this info. Why are you using a single pattern cam in an LTx motor, just curious.

Lift with 1.6s 0.528/0.537

112 LSA

I appologize, I am a horrible typer!

Thanks.

Whatever springs ya get get retainers and locks too. I didn't and it cost an engine.
Call the cam maker for recommendations on springs.

10308 kit. JMHO :cool:

Re: Valve Spring Questions
 

26918's are the best choice.

You need to do some more research as those wont work with stock retainers and while stock locks might work I would think a set of +.050s would be better. I agree with Bret that they are the right springs for the job, you just can't use them with the parts you wanted to.

I can't understand.. We can use 26918 for a smallest cam to a big cam.. Its very usable.. What is the end limit specs for 26918??

Re: Valve Spring Questions
 

depends on the RPM and lobe profile. If you get the 26918's get retainers and locks to go with them.

What is the part number of titanium retainer for 26918? Everyone says different thing..

Re: Valve Spring Questions
 

Unless you plan on spinning 7 grand, you might want to spend your loot on something other than titanium retainers. JMHO :cool:

Re: Valve Spring Questions
 

One of the key benifits of beehives is the smaller and therefore lighter retainer being smaller a switch to titanium will net you a whole lot less weight savings than it would with traditional springs and retainers, by the time they become a remotely good idea I would think a rev kit would be a better way to spend that money.
