Gathering parts for my 2.3t swap. a few questions

[Demented4.6]

Well i got the TC stripped down and now i have a complete drivetrain. I have seen a few people who used ranger roller cams and such as an upgrade to the TC cam. My question is : i have a 91 mustang 2.3 which has the DP roller cam, can i use that cam and roller setup?? anything i have to modify for that?? Also where is a good place to get a 3" downpipe

Yep, you can drop the cam and followers right in. Stinger has a 3" DP, I think, as does Sacramento Mustang (IIRC).

am i better off sticking with the stock TC cam or changing to the Roller cam from my 91?? I just don't want to kill power but help make more. Also when i was looking at the injectors they are all black. no coloring at all. How do i find out if they are the 30# or 35 #?
