my 73 dart that I posted a pic of the tunnelram linkage ran 10.49 in the 1/4 with super stock springs and 4.30 gears. for tires I was using the M/T ET street radial pros in 275/60/15. I think the car would of been faster with the 4.10 it had in it before, but I blew them up on the cars 4th pass down the track after getting it running.lol I had the 4.30 left over from a different car, so I used them. I didn't have a lot of money at the time, so I used a 9.5 Dynamic converter. which was the wrong one for my car, but was all I had at the time. it would flash stall around 4400.the solid roller cam I was using should of had a 5500 stall. which I latter on installed but never got to race the car before I sold it. I think the car had a lot more in it but never got the chance to find out. best of luck on your build and I look forward to more updates on it.
