I was running the 456/457 Superstocks and 275 ET Street Pro's.
Hooked pretty well with SS's but the Cal-Tracs are more consistent.
I have run 11.20's with both at 121-ish mph. Best 60 ft.'s were in the 1.54 range n/a.
The latest Made in Mexico SS springs will NOT last. They bend into a lovely S shape after a couple of seasons and lose arch.
'63 Dodge 330
11.19 @ 121 mph
Pump gas, n/a, through the mufflers on street tires with 3.54's. 3,600 lbs.
10.01 @ 133mph with a 250 shot of nitrous an a splash of race gas. 1.36 60 ft. 3,700 lbs.
