In a word....yes but it would take any and all historical value out of the car. And you would need to be sure of the integrity of the pipe before adding more pipe to it as it's 50+ years old. Heres some examples of Lyndwood Eliminator II chassis all from the 1959-1960 era and one later 4 bar lyndwood which as the last style Bilbow built. the yellow flathead is a 96"wb eliminator II, the blown green one is a 130"wb eliminator II, the silver & blue blown chevy (mine) is a 98"wb eliminator, the gold one is a early 60's 4-bar small tube lyndwood Eliminator III and the purple rail was an original eliminator II but has been heavily modified to pass NHRA tech and now it is what it is?
