A friend of mine bought a '57 Stude Lark to build for Bonneville. Luckily for me it came with a '64 300 in it with a new set of full length headers attached. They are not homemade from what I can tell. Is Poston the only company that made a full tube header for the 300? I am hoping these are Poston made and will fit my '67 Lark. Any input is appreciated.
I suspected he wanted full length on the assumption they would make more power than shorties. On street systems with mufflers that is doubtful based on some testing. http://www.sandersonheaders.com/tech_get_technical.php
