Quote: I think here's the weakest link. Put my guess in the 560HP/530TQ range.
Schoenfeld 1 5/8" 1 3/4" step headers with a 3.5 to 3" hillbilly merge
Consider it noted. I think your guess is quite sound according to my experience with the 4" arm combo. J.Rob
I don't think the header size is that big of a deal. Everybody thinks they need a 1 7/8" header with a striker but I usually see a huge hole in the torque curve with them. The extra couple of horsepower up top with bigger headers may not be worth the loss down low.....
