Default LE3 questions..

I got a 97 Z28 and im about to pull the engine out and send the heads off for the LE3 heads and cam. I know I need to upgrade my stall ,throttle body, and injectors(if yall know of any sites where I could get those things that would be very helpful).But do I need a bigger intake manifold,and a bigger mass air flow sensor for the bigger TB?

Before you go jumping into the LE3 package.... whats the rest of the mods in your ride? Like what are you thinking about in terms of stall, max RPM, tires, gears etc...

Yeah stock bottom and the LE3 heads and cam are tight in terms of PtoV so I would defiantely check that . It's really ment to go on a 355, not a stock bottom end.

Brett is right though, if you're going to run a 350 with a stock bottom end,
go with the LE2. It's designed for that application.
