Well I have the harwood 210's on and it does the job. Closes without straining the hood and opens all the way. Thanks for the info and I'll never tell their Chevy parts. Dilemma solved.
The big block and the LA engine use the same thermostat housing, I have a hemi and a 74 318 and both have the same size thermostat housing. It's the magnum engine that uses the smaller thermostat housing. The bolt hole CL is 3 1/4" on both therm housings. Unless you have a magnum manifold on...
I have 10 binders full of Mopar magazines from the mid 80's when they started publishing them. The only solution maybe to take them to a car show, if you have dedicated Mopar meets, and try to get rid of them that way. I'd be willing to give them away so as not to have to put them in the recycle...
A meziere #WN0028U is a thermostat housing that gives you a 3/8 ported opening. Summit has it. I used it on a Gen 2 Hemi because no water in the manifold and needed Temp. sensor for F.I. installation.
And if it doesn't have them I would definitely recommend putting them on because of the amount of traffic and every other car having them and having to make a panic stop you'll definitely appreciate having Discs. Here in NY a slight hill on a parkway and everybody is stopped on the other side...
My shaker hood is an AMD reproduction. The 2 springs I've tried don't work, flat hood and fiberglass springs. I'd be willing to try the Harwood spring if it brings the hood fully open and doesn't look like the hood is going to bend.
With the Harwood 210 springs do they pull the hood all the way up? The fiberglass springs don't, I have to push it up manually, but at least the hood doesn't look like it is going to bend at the hinge. I'll never tell they are a Chevy part.
Whoever designed the hood opening on the E bodies should be shot. The hood hook is so low I always hit my head on it, and that was with the heavier spring. Now with the fiberglass hood spring it's even worse. The A body, Duster hood almost opens 90*. So why didn't the A body designer design the...
The Cuda had 2 different springs that I'm aware of, the one for the flat hood and one for the fiberglass hood. The flat hood springs make it hard to close the shaker hood and it looks like the hood will bend at the hinge. The other spring is what I stated above.
After the lighter springs were installed, fiberglass hood spring, the hood doesn't open as high as with the heavier spring. But it relieves the amount of pressure used to close the hood with the standard springs. And with the heavy spring always looked like the hood would bend at the hinge point...
