This will also give us the spring rate we need (which apparently is 400-500# with the big engine).
I don't know what their motion ratios are, but this should put you around 250-300# wheel rates. This is equivalent to 1.06-1.12 A body t-bars.
Firm Feel shows the 1.12" A- body bars as a 300#" wheel rate, That is what they recommended for my car. '68 Barracuda 400 B engine, aluminum heads, water pump+Housing, Manual steering and brakes, glass hood, battery in trunk. HTH, Steve
