Nothing currently. I have done a couple with the Pontiac Iron Duke 4 bangers, both were Track T's and both were neat little cars!!!! Built them many years back, like the time of the last great fuel shortage fiasco, doubt I have pictures anymore though..... One was built with a 1 1/2" X 3" rectangular frame, the other was done up with a 1 5/8" round tube moly frame with an old style Franklin quickie and sprint car style torsion bar suspension..... Would be a lot of fun now with all the goodies available for the four bangers!!!!!
