Not quite if you read what Yunick said back in the early 1980’s.
He said the Cleveland was 10 HP up on the SBC and the Chrysler was 8-10 up on the Cleveland.
There is more to making horsepower than a giant intake port. The W2 gets crapped on because it’s old and iron, but even by todays standards of low port heads the W2 kicks *** on most everything.
