The motor Street Rodder built was one of 3. They were all 390's and the one you're referring to, the one that was stolen, was stroked to 431 c.i., (4.125 stroke, 3.080 bore) with a Crane Hyd. Roller cam, 220/226 , 9.75:1 compression and Edelbrock Aluminum heads (reworked). It produced 525 lb-ft between 3,800 and 4,200, and between 2,500 and 5,000 rpm averaged 500 lb-ft. Peak H.P. was 457. "Not bad for a pump gas eater with manners mild enough to run an automatic trans. without idle problems."
