Default meth vs e85 cost wise?? for stock bottom end

Planing on spending money on the car here my setup
98!! Ls1 m6 turbo 7# 500rwhp 530tq on 42#inj one 255
I read up on both of these and my question is if im able to just buy 80#inj, a regulator, e85 filter, and twin255 pumps would be fine on stock lines ?
Or would it be better to get a alky kitt and twin pumps
reason is im spending money havent got the car to the track at all it mostly sits in the garage but i like to take it out on weekends and i cant really get on it bc it leans out after 4500 rpms ...

any one else run stock lines unmodded on e85 my guess is it should be ok on the plastic lines but not on rubber one in the tank
so far the expense comparison

e85
- 80# inj 450$
-twin walbros 250$
-regulator 200$
=900$
meth alky kitt
600$
twin walbros 250$
=850$

Stock lines and rails will support over 850rwhp on e85, we've proven that.

Buy a Mallory 4305M regulator as its cheapest good one you can find IMO.

Any pix on how you set this up on your car?

also I thought you used a 98 corvette fuel rail on a build of yours?
If you did what do you do for the mallory regulator?
