sbc stocker valve springs

Bill Bogues · 02-18-2014, 11:20 PM

Anyone willing to share what spring is being run on 305-350 engines. I try to get 200 closed and 400 open on our engines , but it's hard to get that much pressure without adding over .200 worth of shims. I've been running the 941 Comp springs but there too close to coil bind to suit me.Is there anything out there in a 1.260-1.290 spring that has around 200lbs@ 1.800 --400@1.400. Thanks for any replies. Bill

Isky make a good spring. Made the change from K-Motion to Isky Tool Room and live increased 3x. 200 on the seat at 1.800 might not be achievable but if it needs that kind of seat pressure maybe look at some lighter valve train components within the rules of course. Lol

PAC 1409X beehive. They are the new version of the very good 1409. They just start out higher with the same spring rate. If you have not checked them out, they are worth a look. We beat the crap out of them and they are really good and durable.

Not sure if I would feel confident using those locks on stout stocker springs,but that is just me.

The nice thing about the beehive springs is that they are also lighter. PAC has the lightest design retainers as well. Light + Strong =Fun!

how about the 1218x pac beehive?

james schaechter · 02-19-2014, 11:35 PM

I am sure the 1218x is a good spring for it's application. I have not tested it. I will say this. That spring has a lower closed pressure and a much lower spring rate. I would not use something that low in any of our stuff. Remember that some of the lowlift stuff like we run. 399 lift for example requires a cam lobe that is pretty square. The higher pressure is necessary to keep the lifter on thecam. Floating valves is a bad bad deal. There is no shortcut. You need to maximize your valvetrain to make power and also to prevent breakage. The 1409 and now 1409x is designed for the abuse we give them.
