You dead set on those springs? The open rates on those Alex springs looks pretty weak, considering stock springs are at 230lbs open..i think the stock rate is like 315lbs/in if my math is correct...i wouldnt run those...i would run from those...
ive been using:
118Lbs @ 1.950
Coil bind- 1.320"
Open- 375lbs @ 1.380"
457 lb/in rate
Install @ 1.880" will put you .083" from coil bind
~150 on the seat and ~370 at lift
1987 Notch - N/A stock 302, TFS heads, Holley Systemax, FTI cam, Astro A5
Best so far: 10.92 @ 123mph with a 1.49 60ft
