I can envision you ending up at 23% or more overdriven and E85...

Correct me if I'm wrong but 10.0" crank pulley = 28% OD right? I've been in contact with a local tuner who said 850-1000cc injectors and stock FP will be sufficient for my mods. He said I'd only need new FP or BAP and 1300cc injectors with e85. Currently I plan to stick with 93. Or was your response just directed towards me going e85? Sorry made that confusing lol

Agreed on the injectors- get 1000cc at least, probably 1300. Along the same lines, one thing you are missing is a BAP. Your fuel pump will need help feeding that 10" overdrive.
Also, I'd step up to 2" headers since you're doing it from scratch. If you ever decide to get up into the 750+ range, the 1-7/8" will hold back some ponies. One test I saw showed a 30 rwhp increase going from 1-7/8" to 2" on a car that was originally around 830hp.

Well I spoke with a really well known tuner who's local to me and very familiar he's with GPI performance. He said 850cc injectors should do the job but get 1000cc at least or 1300cc if I plan on e85 in the future as well as a dual 450lph FP if I plan on going e85 as well.
If I just plan on staying on 93, will I still need 1300cc or will 1000cc be sufficient? Also still need a BAP or dual FP if I'm only running 850-1000cc injectors? My tuner said the stock FP should be good unless I go e85 or go crazy big on injectors. Also will def keep in mind 2" headers, I just heard of fitment issues. Not sure if I'll be going 750+ but I guess the HP bug will bite me like it always has! Thanks again for the input!
