I have a LY6 that I am going to stroke to 402, use the stock heads (maybe go larger on the exhaust vavle) stock intake and TB. Driver's side madifold and log type passenger side with a Precision 7675. 4L85E transmission (still undecided on converter), 14 bolt 6 lug with 3.42 and I plan to run 28-29.5 tires, spindles and double adjustable coilover Viking coil overs in the front, flip, C notch, and smooth bore double adjustable Vikings in the rear as well. Boost, extent of head work, and compression is still up in the air. My question is how much fuel pump and injector will I need to consider? I realize my info isn't very thorough but I need to have a ballpark where to statt looking

 

How much boost do you plan to run? Why the 7675 on a 402? Just curious.

 

on 93 a single 450 and 80# injectors would do. On E85 youll probably want 1300cc injectors and 2 450's.

I'll echo pats question. Thats a fairly small turbo for a 402.

 

Start out with dual 450s and 96lb injectors and go from there
