    3500 exhaust manifolds, mild ported

    I have a pair of 3500 header style exhaust manifolds for sale with mild porting work done to them. The outlets where opened up from 1 3/4" to approx 2" on both manifolds, thats all the porting I did to them.

              could you please get profile pics to show how much they stick outward from the block on either side?

                  I will see if I can do that, if not I can get some measurements off a cylinder head if that helps?

                              I've heard these don't fit 3400 heads. True? False?

                                                  hey now. I've got a GenIII motor running on MPFI and it spanks most newer 3x00 equipped cars. MPFI FTW

                                                  FWIW, these are useless withough a flange. Which are a BITCH to find, you have to get to the cars at the J/Y before they pull the motor out, and that's hard to time just right. That's why i have a pair of the fronts sitting in my garage for the last 6 months

                                                  Cammed 3400 --> 224whp 210wtq

                                                      A flange is easy to make out of 3/8" or 1/2" steel if you have access to a mill (or would be pretty inexpensive at a machine shop). Then you could just weld them to pipe.
