Dale Ray Passey 5pts First of all the first Z/28 was a 1967! also the 302 was rated @ 290 because the government would not let Chevrolet put the Camaro out at the higher rating. It was actually putting out 520 bhp, So that's why Chevrolet rated it at 290 bhp. they only built 602.The Camaro did win the SCCA TRANS -AM SERIES Twice but it wasn't a 68 that won both races. 67 and 69 were the winning models mustang won once .
