I am getting them from a good friend of mine for a very good price. They still have 2-3 years of warranty left on them. I like them because they hold up very well. There will also be a signifcant amount of weight removed when I get my stock cast iron manifolds off. We may have to get some custom tails made up or have the one's he has modified but I am ok with that.

Ah yes, sorry i missed that, you will be happy, they will last about forever and just so you know you are looking at well over 200lbs weight savings on twin engines.

Me engine guys chuckled and told me he almost tossed the first one because he wasn't paying attention and was expecting the stock manifolds, they are a little less than 60 lbs lighter ea.

Excellent choice.

Being in salt I looked hard at those sm manifolds but went with headers. My only thing too add is that I can't believe you went all that time with the stock manifolds. You are gonna be smiling ear to ear once you put those on.

Simple effective solution:

Dart makes a very nice Iron Eagle replacement head that is minus this exhaust heat riser port for the BBC engines and it flows out of the box much better than the old GM head. Its not really effective in my opinion to put money into the old GM head when a head like the Dart iron Eagles can be used at a very reasonable cost versus putting bucks into the old head.
