Hi- what is a fair price for a used set of BBC power flow? They are black base with chrome tails. There are some scratches, but very good parts. Thank you

I’d think 1,200 - 1,500 max fresh water.

I bought a set for $800, but then I had to buy the oil filter relocation kit and the PS pump bracket which was a couple hundred dollars. It all depends on whether you are going to include the 2 key pieces or not.

Thank you

Check the water jacket holes in both. If they are round, the manifolds are probably older. No issue, but older. Newer ones have triangle looking holes in them. Probably not a big difference in either, but just some info to have. I was exhaust dumb early on and ordered a brand new (and expensive) set on my old 454 years ago and like snapmorgan I had to use the IMCO ps bracket to get clearance. With my 502, I had to buy the oil filter relocation kit. The last set, I bought everything piecemeal. Manifolds first and then had to search for risers. Together, I believe it was about $1400. However, I found that someone had shortened one of the risers and did a crappy job of it. Sent it back to IMCO and they made it like new again for about $150. There is always a catch with used stuff. Good luck.
