Coil springs

[brian95]

I have 14-130 coil overs in front with 10-150 in back and my front is adjusted as far up as I can go the front has almost no bounce at all. What size is everyone using it’s a dart 363 manual rack race only car. I was told to try 14-175 in front I will be changing to TF R 225 heads with 2inch pri headers so I’m just locking at the added weight compared to my TW170 heads with 1-3/4 headers I have now. The springs with on my stock block 347 but I have added weight with new setup. If I push on my front it just stays down and don’t rebound up. If I lower down springs I can’t get a floor jack under it due to being soo low

Aren't those drag racing springs? My understanding is they store a lot of energy until the car accelerates to and then the front end pops up to transfer weight.

But I'd think there would still be some rebound. If the suspension is getting "stuck" I'd start looking for components that are supposed to be moving, but aren't.

They are drag springs they had more bounce with the 347 but when I added weight it dropped and don’t move I was told from upr it takes 130 move a inch and the 175 with the added weight might be better due to added weight just looking if anyone has had the 175 it ran a 1.50 60ft with the 347 and now a 1.47 with the 363 maybe il just mess with what I have alittle more and see
