front lowering
Is there any way to lower the front end without cutting the springs or spending big cash on coil overs? I've seen plenty of posts talking about cutting or spending big money, but can't afford that right now and don't want to cut the springs. I've also heard that the F41 springs for a big block are 1 inch shorter sprung length, but that the actual amount on the car with weight is not really a noticeable difference. I have a small block 75 coupe. The current ride on the front is about 1.5 inches too high IMO. The back I know I can add longer bolts and have purchased them. Is there any thing I'm missing?

It will impact the spring rate somewhat, but considering that you're talking about a 44 year old car, that you most likely don't know the "pedigree" of the springs on, I wouldn't worry all that much about any change in rate. One thing to remember, is that in order to keep the springs in "proper register", in both the frame and lower a-arm pockets, you need to cut an equal amount from each end of the spring.

I just went through this. I swapped from tired stock springs to 550 lb. F41-style springs. My front end raised a half inch. Had I cut one coil, they'd have been too short. Perhaps half a coil would have been perfect.
I'll go with coil-overs next time, whatever the cost. I do like the stiffer spring, so there's no urgency.

first check frame height to the ground. there is frame height and body height. i currently have a 75 that i got cheap cuz of a nose hit. i straightened frame horns and vac tank and put it back together. i have 29 inches on the right and 30 on the left. i have some tweaking to do with frame horns, but i am sure that lowering the vacuum tank (the rad support mounts to it and nose and hood mount to the support) will get me closer to where i need to be. 74 frame height specs. https://www.c3vr.com/member_pages/44...4427/specs.jpg make it bigger is easier to read. wheelwell arch is 27-1/2 to 28 as delivered. looks like i am around 8 inches frame to ground.

On my '75 I bought the 550lbs. springs and cut half a coil. Lowered the car 2". It rides more stiff now. The only way its not going to change the ride feel is by buying coil overs with a soft spring.
Is my vette stock?? HAHA

You could get some VBP springs like these, if you can find them used and be able to set your frame height and spring rate. https://www.corvetteforum.com/forums...ale-trade.html
I have a set like this front and rear with a spreader bar up front and it rides great, stays flat in a high speed turn and couldnt be happier. Just spent the day on a closed track for the first time and it was amazing.
