E85/intake

sorry don't know if this is the right place to ask. I'm looking to do E85 conversion i already have long tube headers , corsa catback and a tune once i decide if E85 is worth it. is it worth to do E85? also will i have to get bigger injectors or change them at all? I'm looking to get a good gain of horsepower out of it. my other option is to do intake , long tube headers , corsa catback and tune. whats worth more intake/exhaust/headers/tune or E85/exhuast/headers/tune? sorry for so much writing.

Stock cubes NA LS3, definitely not worth it.
Gains will be negligible.
Don't believe the bs threads where people say they gained 40rwhp

E85/intake

Juan you just need a properly spec'd VVT cam with IVC starting below 38°, retard it a full 7° after mid 4K and it will go like a hellhound on both pump and e85.
Effective dynamic compression is the key. 5% typical improvement, 7% with tuned bolt-ons.
I jumped comp to 10.2 effective DCR and get similar economy to gas, 600 HP, stock injectors.

Cam first after full exhaust and headers. I've always heard there is very little to gain on e85 while NA.

Not much gain.11rwhp on my ls1 gto.found so much inconsistently in the e85 at the pump,can range from e50 to e85.depending from winter blend to summer blends.thinking to get it to work best,need to convert to flex tune.hope this helps.

It produces greater BMEP, ITE and lower BSFC with raised cylinder pressure vs knock-limited 93. So decent cam with EIVC as above, multiplied by loosening the TCC and voilá you have a powerful sprinter:
