Heres what i did ....got a solid calf. car (1970 swinger custom) it was a 6cyl a/t with air....when out and bought a RUNNING 1970 New yorker 440 4bbl (factory holley).Then got a big block(?) k-frame with spool mounts. Pulled 6 added 440 4bbl with air.. schumaker headers >>>>DON'T waste time looking for anything else..just check the big block manifolds that were just on here sold for over 600!! And i thought we were all friends here<<<.everything bolted right up !! This car still has the org. paint and color key steels with org.dog dish hub caps ..sitting you would NEVER know ..running draws plenty of lookers....WHAT What ...
