Quick valve spring question. 
Quick valve spring question.
Just because they have sufficient lift capacity does not mean they will work. Such thinking is comparable to the old "3/4 race cam" mentality.
I am not commenting on the actual suitability just on the lack of proper reasoning applied by the last poster.
IMO the 306 is a bad choice so I wont help you make that choice.

Understanding how to pick parts is more important than a yes or no answer. The old "give a man a fish he eats for a day, teach a man to fish he eats for a lifetime".
Compare them to Comp's recommendations then realize Comp's recommendations are WAY off since the cam needs to sping 1000rpms higher than they admit and they are recommending based on 1.5s not 1.6s like almost all of us actually run, both significant details that will require more spring than recommended to control.

yea, the springs will work. I would use some Comp 4771-16 locators and set them up at 1.800 though since they have those big "heavy" retainers.
Lots of people have used this cam/spring set up and it works for them.

That is a normative statement. Not everyones goals match yours, and you know nothing about what it's going in, or plans for said vehicle. There is a reason I only asked about the valve springs, so people like you didn't start preaching that it wasnt AI stuff. It cant possibly run well without being AI.
But look llyod comes right on in and just answers the question. LLyod your a really helpful and stand up guy.

The ? was asked and a very qualified response from Lloyd was given. Unfortunately the Caprice owner could only criticize the content of the question without offering any qualified comments.
A titanium retainer would be "lighter" but I don't know if one is made for the 10308 spring. Might want to check with Crane cams.

For the record I saw the post yesterday and did not post till I saw the flawed logic being used to recommend a specific spring. I was not looking for something to critisize, if I was I would have posted yesterday.
Roger, if I am so bad put those doubles back in your car since two highly thought of professionals told you they would work and this idiot carpenter was the first to tell you you needed those beehives. Understanding HOW to make decisions seems to be a lost art and all of you would be a little further ahead to learn it.
I went and looked at the specs and the Crane springs look to be a better choice than the ones Comp recommends, Comp recommends a LOT less pressure and I can pretty much guarantee those would not work.

Cool well they are going on then. My buddy should be real happy. hes building a motor using junkyard and cheap parts for a truck and hes been getting some bad *** deals. Should run well for whats invested.
I have a 10308 kit laying around and I told him he could have them if they'd work so he'll be pumped.

If a truck does that mean non-LT1?? If so the lower rpms of the dual plane intake he will likely use will make the cam easier to control.
When talking parts people need to offer more information because take the same cam and put on heads with hollow LT4 valves and it will need less spring than a set of heads with Ferrea valves in it, intake manifold affects rpm thereby affecting how much spring is needed.
Far as retainers look up the dimensions on the crane retainers and then look at Competition Products for options, they have some titanium stuff.

He found a single plane at a swap meet for like 50 bucks so hes running that. It started life as a Gen 1 vortec motor its kind of a frankenstein motor now.
His machine guy said he had somethign special for him in the works for the heads but he said Lt1 springs will work. We have yet to here what is goin on with the heads but for the price hes getting them if they perform ahlf as well as the guy says then they are well worth it.
Hes got next to no money in this motor.
All the machine workw as done free he just had to pay for bearing and a little bit of money for heads. He found a used eagle stroker crank, and rods.
Ive got a torn apart 383 layin in the garage and im tempted to build a junker. Cheap as possible and see if I can squeeze 450 out of it.
