Not a bad idea 88. I would think the pistons on a cab over are heftier than a hood piston. I’ll look into that today. I probably have most of the stuff available for airlines and splitter valves. Just a matter of figuring out which size pistons I would need
Heavy hood, how can I make it easier to open?

Before changing springs for stronger tension, or shorter springs. You should look at the brackets, and locations on both ends. I’m not familiar with 359’s. Doesn’t matter. Same principles apply. When hood is closed, springs are stretched out to their fullest length. Sometimes they get put back in the wrong spot, after a repair. If You can lengthen the distance between both ends of the spring, where it’s attached, so the spring stretches out more, when closed. It will open easier. If you can’t increase the distances, another way, though less desirable,( more of a quick fix ). Would be to bind a few coils (however many it takes) together on each spring, on one end, both ends, in the middle. Whatever seems to work best. Don’t want to stress the ends too much, and have them break. Could be dangerous, if it hits you. A few inches in the distance makes a big difference. Ideally, they should be stretched enough to open easily, and still fully close. Post a picture if possible, with hood open, and each end of spring where they’re attached. Might be a simple fix.

I understand what you’re telling me but how would you suggest I bind the coils together? And if that works for me, and my parts shop has a spring close or exactly to that length, wouldn’t that be a safer choice. I have a 379 exhd and it calls for the blue springs. I’ve changed the springs, studs on both ends and replaced all the rollers and rubber firewall pads. Other than the J hinges it’s all there but heavy.

I was thinking something like these. 2 on the ends of each spring.

There is an art to adjusting a Pete hood. Most put it too far back which is actually set by the rubber mounts on the J brackets. The side rollers you just want snug. It should also sit square when open and not hang off 1 cable so to speak.
You can modify springs add #### what ever till hell comes home. You may make it easier to open but you still haven’t corrected your major concern. Proper adjustment is the life of a Pete hood. Once they start shaking apart there is no reversal and it gets spendy.Tug Toy, Oxbow and Rideandrepair Thank this. -
Hey R&R I see what you mean now with the clamps. I was researching the length of the springs. The blue ones are 21” and the black ones are 20”. After I change the J brackets and hardware I think I’ll try the shorter springs along with a proper adjustment as per woreout. I have a gap of about 3/4” to the firewall when the hood is closed and a pinch lower than the firewall cowl. I’m sure with the new parts it will be different but what is the proper gap between hood and cowl
Rideandrepair Thanks this. -
I’ll get you a measurement
