So, 550hp or 460 rwhp is good for a 402. That pretty soft. Mark H has a 385 with stock cams that puts out more. 368ci with stage1 cams is 550+.
Not saying this or any "old school" is junk, it's just very mild. Or did not get cammed or headers? Maybe it still is blowing through stock manifolds for smog check? I dont know..
Still is a nice car for money, dont care for purple.
I thought Black Rose would have been more red
