CPPA headers

Kim, it's too bad you are so far away, and across the boarder. I have some headers you could try on your 543.
I have a set of semi-fenderwell custom Marco headers, off of a big block 440 duster. They are 2 1/4 tube, four inch collector, and equal length. Front tube on both sides goes straight down Tru the k-member, one side has two thru the wheelwell, the other has three. They were probably way big for a low eleven second car.
This is NOT a solicitation, I wanna keep em...... but I bet the would work good on yours.
