Whats the difference between the listed intakes ?
Read somewhere last year where runners on TM5 were different or larger than the Torker or Torker 340 intakes ???
Out of the Edelbrock intakes, use the TorkerII-340.
On the aftermarket intakes, the M1 is reported by MP as a few HP better than the Holley Strip Dominator because it really is a copy of the Holley.
The Offenhauser is also reported and talked about by MP as an excellent intake. The Port-O-Sonic, Holley Strip Dominator are writen up in the engines book by MP with suggested mods to be done. Popsicle sticks on the intake floor to help adjust and equalize runner flow.
