I mentioned earlier where a marine engine builder had ran a set of stainless marine exhaust like tims, up against dyno headers, power dropped from about 640hp, to 600hp with the stsinless marine exhaust installled. I believe it was a 502ci build.

Wasn't it a tie at 568hp between the 741 and the 168801 (same spec but on a 110lsa)? Only mentioning because I said the 168801 (d)...

That's pretty significant. I'm surprised as I've heard the Gen3 SM are good for 800hp? Or is it because the dyno headers are dry?
