    I am going to be doing a top swap sometime this racing season, and while gathering the parts, I am wondering if I should buy 42 lb injectors, or just use stock L67 injectors at first. During the top swap, I will be installing a Gen V, VS Cam, and headers. I have a MPS that will go on the Gen V as well. Will I be beyond maxxing out stock L67 injectors from the beginning if I go that route?

    edit: I am also considering a Northstar TB and tuning for E85 in the future.

    I'm pretty sure you can get away with stock gtp injectors but if your going through all that might as well put 42.5's in or if thinking about e85 put 60's in. Also I'll have some top swap parts available soon if your interested pm me.
