just a thought thinking of going with a 383 short block with the lt4 conversion kit off of summit. wondering what else would be required along with this computer, fuel and air ratio's, would i need bigger injectors, i beleive u do if you have a cam how does this affect. the overall system? being im dealing with a 4th gen z28thought this would be a good postthanks.

 

A 383 will nned larger injectors and why would you bother with the LT4 cam when your doing all that work? There are better cams for that application than the LT4 that will give you much more power. The LT4 heads are good units though as is the the intake. You will for sure need a computor tune after this is all done.
