Drag racing setup vs Street Rod? Shocks or ??

What I'm going to say is for reference, not to brag.
I have a 64 Sport Fury with a 440 has a cast crank. .505 intake, .515 exhaust
3.91 locker rear, 3000 stall converter. Rpm intake, with a 750 race demon. 1 3/4 headers. 1 1/8 front sway bar, .920 bars, KYB shocks. Nothing removed, or disconnected.
I went 12.12 @ 110 mph.
So, I think your combo has some serious issues. Changing the suspension will improve the performance, but will not fix whatever is the main problem. I'm not sure the rockers will either.
