I can move it to 5.0 Talk and link it in http://www.stangnet.com/mustang-forums/761371-official-progress-threads-thread.html
Would you like to rename the thread to something referencing a progress thread? If so, let me know what to title it.
I have been following for a while. I am interested to see how your results come out. I am hoping to eventually get my 427W combo in the 600rwhp range naturally aspirated. I have run it from 450ish up to around 500rwhp before I needed to address what appeared to be some airflow restrictions on the intake side. Now after having some abdominal surgery I am in limbo for a while since I can't do any torquing.
I think going carb is definitely going to save you a good bit of money and allow you the best chance to feed it the air it is going to need. If you go EFI, you would more than likely have to run a FAST if not for tuning concerns, but then likely so you could run a carb style 4 barrel TB that does not use a mass air meter.
I switched to a FAST bank-to-bank and Accufab 4 barrel Dominator style TB which required having the Super Victor EFI intake fabbed to accept the TB.
Buy a good set of micrometers and a dial bore gauge and hand measure everything, throw the plastigauge in the trash.
I asked if he would refer anyone to build it and he suggested that he would give me all the tools and knowledge to do it myself, so I'm going this route.
The only problem I have here is that I do not know all the allowances or clearances. I'm thinking that .003 is the max, but what do you do if your over the max, have the crank turned? I have read after the fact of buying all Eagle stuff that they have been having problems with the cranks not being perfectly round and having an oblong shape journal. John my machinist is checking all that and if it needs turned, he will turn it to be perfect. He is getting all the bearings and rings that I need. Thanks for any input here.
