Under IDEAL engine only dyno conditions the LT4 HOT kit with the GM intake made 425fwhp, nobody is claiming the Edelbrock intake is anything beyond decent and sofar the results look poor for the price on it.
A good ported LT1 heads and cam package can make 400+ at the TIRES which is much more than 425 flywheel.

Exactly what is an LT4?? My friend claims he has a 96z with an lt4. I have heard of them buy dont really know much about what they are exactly supposed to be. What makes tham better than an lt1? Or are they any better?

The heads flow a lot more than STOCK LT1 heads. 250ish vs 210ish. The hot cam used to be "hot", now it's sort of just ordinary. It's not bad mind you, it's just that there is a lot of better stuff out there. A bone-stock LT4 'Vette will dyno near the 300hp mark at the wheels, about 45-50 more than an LT1 'Vette. It's a solid package, but NOT WORTH the money you'll pay. The heads are like 1300-1400 bucks, and you NEED the LT4 intake because the ports are slightly raised. So figure 1800 at least for the heads/intake. Now go to AI or LE and see what 1800 bucks will get you, lol. Your money is better spent on the aftermarket porters.

The LT4 head ports are NOT RAISED they are taller, the floor is in the same spot, and the LT4 intake is internally the same as an LT1 intake meaning the ports are smaller than the LT4 head ports, there is just more material above the port to seal above the taller port in the head. Guys have used LT1 intakes on LT4s, the sealing margin is narrow but it has been done.
