Good going there, as a 1st time builder and having limited $ to deal with like this aproach. I am currently build a 57 chevy truck , like you been doing lot of swapping and deal making. I got a rolling chassis only, no motor or tranny, but guy thru in a old carb that could not use and I sold it, and bought a 283 from a guy at work, so I got it for nothing. I too are on a budget but think it is in reach to do same. Keep up the good work and progress reports.
