early A-BODY 1-5/8" x 1-3/4" SMALL BLOCK STEP HEADERS
we put a set in a 66 baracuda. thy are tight as hell.. master cyl was fine in stock location.. i think they made them with small torsion bars though.. the cuda we put them on has 1" bars and its super super tight around the torsion bar. took a long time to het that engine positioned just right.. i think if i did another small block early abody i'd go with the smaller tube dougs headers even if it cost me some power...
