Landrum/Calvert monoleaf question

SmallBlockNova · 08-15-2008, 04:21 PM

I have a '71 Nova street strip car, runs mid 11's, and 60 foots in the mid 1.50s. The car has Cal Tracs, and Landrum 175# monoleaf springs in the back. The 175# rear springs are rated for a 2750-3100 lb. car, but mine weighs 3400 race ready. Is this a problem? The car works well, but I'm worried about breaking a spring. It twists a little bit at launch, but I'm not sure if this is due to my leaf springs moved closer together (minitub) or because my springs are too light. Should I switch to Calvert split 200# springs or will I be fine? Thanks.
