Alston subframe I can't speak for the Alston subframe but I have a Martz Engineering front end under my 69....very similar in dimensions to the Alston. It is set up with a manual rack and pinion. I have a set of stainless American Racing 1-7/8" "D" port headers and the fit is perfect....tons of room to spare and great ground clearance. In fact, I have to give a shout to the folks at American Racing for the finest headers I have ever seen..the construction has to be seen to be believed. I also did not realize how light SS headers were. They also make 2" headers if you are making gross horsepower or have a stroker LSX...I only have a 500ish HP LS6 so the 1-7/8 inchers are fine... |
