The back pressure I had Rob at Fordspeed tig a female 1/8 NPT steel bung on my drivers side header. Its basically a female coupler 1/8x1/8 npt(bought at Goodyear on 49th street in St Pete). I screwed in a 1/8 NPT male to a 1/8 pipe compression. Went to Advance bought a roll of 1/8 copper tubing(used for gauges).. left it coiled up.. and hooked up my oil pressure sending unit to the other end since it was right next to the drivers side header and needed no wiring in my case. pretty simple..

I like the Mustang, but feel the Buick crowd is more tight knit. Maybe because the cars where only made for two years everyone is together more. Less hate. The Mustang crowd has too much dislike mixed in.. carb guys hate EFI guys.. SN95 guys hate 5.0's.. Nitrous guys hate turbo guys.. big blocks vs small blocks..Cobra guys hate SN95 guys.. 05+ Mustangs feel better than the earlier ones.. The have each one of the body styles separated.. when it all should be the same. I find it hard getting involved in the Ford communitty.. its alright.. i'm doing my thing and enjoying the car.. no dislikes.. it would have cost 2X at least to get a Buick to run this like.. and be very specialized.. this is a motor I threw together in my garaje 3 years ago and now has 300+ passes. Really neat i've had several local shops help in the process like All American, Fordspeed, ProFab, etc to make my life easier. With a Buick.. good luck..its very uphill..
