Help me get into the 12's for cheap

big block all the way but it's not cheap. so that being said, LA360 don't forget the convertor. take it apart in the garage or living room which ever the wife allows. buy a ridge reamer and home take it outside and cut the ridge out then use running water and hone until the bores are nice. go on e-bay and buy a rebuild kit and solid cam & kit at .500"+, also a 750 holley. port the heads yourself and get a good valve job. get the rocker gear off a 273" motor. go back on e-bay to find a old direct connection or mopar performance manual will help to select parts. buy as many used parts that you can. that should get you moving towards your goal.
