Hey guys,thanks for all the feedback, I really appreciate it. I've decided to go with a two-step 2 1/4" to 2 3/8" with a 4" collector. The AlterKtion (to get rid of torsion bars and free space for the dry sump pump) should arrive next week, so I can get going on the headers. I hope to get the headers and dry sump together and stop by Best Machine on the way home to hear this beast sing! Then we'll know what it makes! Today is day 17 of the build, I've replaced inner and outer rockers, trans crossmember, and all four frame rails so far. Floor is obviously still out, and I got one wheelhouse out today with fresh one mocked in place. Finally getting something done on it! Thanks again!
