Match Race 1972 ~ 'Duster 340 vs 'GTO 400'

Had a basically stock 1972 Fire bird Formula 400. Stock other than cam & headers. Gutless. Cool thing about the early Ponchos: all the early ones were set near zero deck. Yanked the stock 1972 7K3 heads off,installed a set of 1968-69 18 castings on it. Compression jumped from 8 to 1,to 10-to 1. This and a moderate narrow lobe center cam. Night and day difference. Cackled& feisty, low and mid range crazy. Nice combo.
