Lifting up a 70 Nova
In this Tech Tip, John helps to sort out some fresh suspension for a customer’s ’70 Nova.
“I have a 1970 Nova. I have a hot 355 small block with a 700r4 transmission, power disc brakes and power steering. The stock springs have been reworked previously to a multi leaf with 6 leaves, because I like a taller stance instead of lowered. What spring rate would you recommend and what arch? I do drive it hard and load it with cargo sometimes. Research says it is 3300 pounds. I was leaning towards 176# AFCO springs or Landrum Springs, possibly the 200# set. Not sure it the true arch is too high or what rate to use to look good and perform well with 255/60/R15 drive tires. Any suggestions? It is a street strip car and I do plan on beefing it up some more.”
Hi Wyatt, You inquired about rear springs for your Nova and expressed a desire to raise instead of lower the height of the vehicle. Our AFCO and Landrum springs are designed primarily to be used for circle track racing but normally in a lower ride height for less body roll. If you are 3300lbs, you could add the AFCO P/N 10620228XHD, (these are a 238# rate) or the Landrum #91721344SP (225# rate) could be an alternative. Be aware that your ride height will also change some with the heavier springs.
