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.

yep, it did have some serious issues. When we did the run seen above, that was the last of the season. When I got it home, one plug wire was off and one was shorted/burnt by the header and the tune for the efi was awful. My son was on his second race ever and left off idle. Much room for improvement. When the weather clears we will get it to the dyno for some tuning.
