i am going to start out by saying i am just going for a time slip i realy dont plan on setting any records with what i wan to build my goal is just to go 200plus mph. i plan on building a hand bilt 1934 chevy roadster like pickup on top of an 1928 model a frame that i have. its not going to be a "RAT ROD" its going to be a full blow diven hot rod that i want to build to run as well. My question is that i want to z the front frame rails and step the back of the frame up to get the truck lower to the ground without sinking the body over the frame. is this something that i am going to be red flaged on or is it ok if i leave all the welds unground and fishplate all the joints?

The rules for roadster classes are that any type of frame may be used....street roadster however, does specify no multi tube type frames though.... think funny car or dragster style type "truss" frame sections here.... class legality is IN FACT only an issue if you set the record..... now, having said that, I have seen many people over the years show up at Bonneville and tell us that they "only want to get a timing slip or brass plaque of such ans such a speed"..... my question is (while looking at the twin turbo Ford small block (watch me on video-Salt Flat Speedway to Dr. Mayf) ... what are you going to to when you achieve that speed- pack up and go home?... this land speed racing has a way of getting you "hooked".... keep that in mind......
I will also say that your idea has merit... and yes, fishplating, gussetting, boxing the inner sides (of channel frames) are all good ideas.... look at using diagonals from your cage support to the area ahead of the "z" in the frame as well.
I was just reminded of my ill fated Bantam roadster project from the very early 1980s that I built a rectangular tubed frame that gave the car a very low stance.... the project NEVER got finished as I was going to have to cut the little stock fenders off to be legal in gas roadster.... I did not want to build a Street Roadster.... the body, part of the frame and the rolling chassis components are still on "display" in my shop.... I had also figured out back then as to how to permanently construct a cage structure into the body and have a removable competition structure to bolt into the car because I wanted the car to also be street legal and driveable in its other incarnation.
Just make sure you have a current rule book which you read MANY times, a note pad and pen/pencil, and WHEN questions arise, write them down and ask.... send them to the SCTA-BNI tech people and post them on here as well..... lots of us on here will try to help you out.
Have fun and good luck!
