The springs will not be too hard on your valve train, and yes you will need new seats retainers and seals. Shimming is going to depend on your installed height and cam lift. On a street car we recommend about .080" from bind.. This lessens the overall stress on the spring and still keeps it at an adequate coil bind height.

Ok, let me see if I understand this right. If I order patriot dual's which have a coil bind of 1.09, my max lift is .603 and the recommended install height is 1.8. If I install the springs and they measure out to be 1.775 then it would be damn near dead nuts with the .080 coil bind. But if I install them and there right at 1.8, then I would have to put roughly a .030 shim in there to get it where I want, correct? Am I thinkig about this the right way or am I way off?

That would be correct. You do need to measure your height with the retainer and no spring first to make sure it is at 1.8 and not 1.75 or 1.85. But yeah your thought is right.

1. No, aslong as you not running way more spring then you need. 2. Yes. 3. No, they are engineered to drop in and go.

So if you have .500 lift or .650 lift it doesnt matter?

JPH

You could use them, but a different spring might be in order though. Depends on cam lobe intensity and rpm usuage, etc...

I'd still feel more comfortable shimming them to .800" from bind.

Y'all lost me right there.

I will install and check the height and go from there. I want to do it right the first time. I don't want it to mess up on me down the road. And plus it doesn't seem like it's that hard to shim them if it's needed. Just time consuming.

TurboBuick6

Just take your time and do it right.

JPH

.800? Don't you mean .080? And .050-.060 is the magic number nowadays.

bstuby

iTrader: (36)

I knew what he meant. Prob just a typo

TurboBuick6

Depends on the spring rate, lift, RPM range and application of the spring. We usually recomend .075 plus or minus .025. If you want to get real technical we suggest to the race guys .005" incriments between pulls to find the exact spot the engine frequency has as little effect on the natrual frequency of the spring. There really is no sweet spot for say.

JPH

iTrader: (2)

Yep you are correct there.

Unfortunately too many people don't take the time to even shim the spring let alone tune it to their engine.

JPH

iTrader: (2)

Yeah, they look at everything as a drop in and go deal, and once there at the chassis dyno they see signs of instability they are kind of shocked. I actually use and sell alot of your guys springs in my own applications and sell them to numerous customer with A+ results.

I saw Ft. Wayne and had an idea I might know you :-)

You might. Hires Speed Shop is the name of my business.

That patriot gold extream kit comes with retainers and locks I belive

I don't know why you would go with patriot springs though. There are much much better springs out there. The longevity of the patriots isn't that great from what I hear. I would just go with the pac single springs.

I'd say that as long as you dont run higher than a 224 cam you shouldnt have to worry about shimming (although you should always check coil bind agreed), its the bigger cams where that really becomes a factor, am i correct in assuming this turbobuick?
