This is planned as a daily and I am planning on running a couple good dyno tunes on an ems in due time and I decided on spray instead of a sc/ turbo since I only plan on spraying during a race and I thnk this hopefully could be a solid mid 12 second car with this list and spray, I also am planning on adding mmr

forged crankshaft / billet forged rods / manley pistons $2,000

With the spray in time and I am looking for someone who can help me get aftermarket cams and an aftermarket intake manifold as I have seen a few forums but never have found an aftermarket website selling them, I also plan on bigger injectors and like I said a great tune for nos and another for dding the car

I just am looking for some opinions and am new to the forums, I wanted a 5.0 to start with but wasnt trying to pay so much for insurance yet I'm 18 and the prices just dont fit my budget lol I figure to hopefully be a mid to low 12 second car before spray and have a reliable dd and sometimes autocross stang, like I said before I have worked with and had success with hondas and as I have a bit more money I'm ready to work with a newer mustang, I considered a ton of 4.6s and older foxbodys but I am set on building the hell outta the new 3.7 and doing it efficiently, the lower cost of insurance and 30mpgs hwy for now made my decision, also let me know what you may run in a 1/4 and what mpgs you may get with similar mods Thanks for reading guys let me know what you think!
