1968 Match Race '383 Road Runner' vs 'Cutlass 350 Ram-Rod'
during GM testing between Olds and Pontiac back in 67,there was a drag test between a Ram Air II Firebird and a 68 Olds Ram Rod
the Ram Rod spanked the Firebird,and they were not happy
the one thing that really hurt the w-31 was the exhaust manifolds
like the z/28,once some headers were added,and tuning were done,a w-31 was deep in the 13's.
btw,this 383 car did pretty good in it's class
