Congratulations to Jeff Biro for winning the 2007 OSCA Pro Stock Class competition with his beautiful 1969 Camaro Z28. At Rolling Thunderz we were confident that Jeff' was on his way to success after we saw the first 8.8 second ET time ticket in 2005 with the .035 reaction time that demonstrated Jeff's skilful drag racing abilities. The Rolling Thunderz built 598 cid Single 4 barrel Racing engine that powered this 8.8 second elapsed time produced over 1070 horsepower, naturally aspirated, with Dart 18 Degree Big Chief heads modified by Rolling Thunderz.
