I was wanting to know if the conversion was worth it also around what hp am I going to have?
I have a stock z28 a4

The conversion is outdated and not a very effective use of your money.

It has a bit of name recogonition attached to it, but other than that your money is better spent elsewhere.

Here are the two popular choices:

Not worth it at all. Besides, you have about $1500 worth of bolt-ons needed before you start thinking about heads/cam.

While I agree with you, they aren't "needed." True LT4s came in F-bodies without boltons.

You realize that the hotcam and the production LT4 cam are two COMPLETELY different grinds? The LT4 conversion comes with the HOTcam and the production LT4 motor came with a very docile production cam - not the same.

You would be an absolute moron to install LT4 heads and hotcam with stock LT1 manifolds, stock exhaust, stock intake, stock PCM programming, etc. That might be something you would do, but for someone with half a brain, you'd do the bolt-ons first.

Hence why I said True LT4. Not the conversion.

I already said I agreed with you.

Bottom line is it can be done. Nothing you said is "needed."

Could not agree more Ramair. You have to compare apples to apples!

The OP said "conversion." You quoted me when I was talking about the conversion. No one in this thread is talking about production LT4s, per the OPs original post. Your comment about not needing bolt-ons with a production LT4 is fruitless because we aren't even talking about production LT4s! Wow!

Bottom line is, you're a moron.

Heads and cam can be done with little to no other mods. It just isn't recommended if you want to make the most of it.

I brought it up because you told him he has required bolt ons to run heads/cam. Which is only ideal, not necessary. There's a way to recommend things to people without telling them they are mandatory. You didn't learn this in elementary school.

LT4 kit waste of money, bolt ons SHOULD be mandatory before heads/cam

The aftermarket LT4 conversion is definately a mild setup for the cost. It's kind of nice to have the name, and have everything come in one kit, but beyond that it's not great bang for the buck.

Advanced Inductions and Elliot Portworks (AI and LE) have setups that will make more power porting and polishing your factory heads than using the aftermarket heads provided in that setup for less $.

DVS LT1

To me, if it has an opti and reverse flow pump/cooling/heads - its an LT1. I'm not even down with the whole LT "X" phrase, b/c since when did the LT5 have anything to do with the Gen II SBC??? (besides, we're not that cool like the LSX crown remember guys )

The LT1 should have been equipped with 1.6 roller rockers and fast burn heads from day one...

Anyways, if the OP wants to have/say he's got an "LT4", I'd recommend finding a fancy red GM LT4 intake manifold and getting a set of AFR Eliminator LT4 heads. Then run whatever cam an expert recommends.

I think the GM LT4 conversion kit with LT4 heads, intake, 1.6 rockers, springs and "Hot Cam" (.525 lift) was popular 10 years ago?? (When did they disco that intake?). I remember GM claiming a "proven 425 hp" (flywheel) with this kit. You could eclipse that with just stock ported heads and a good cam.

The LT4 heads are the best stock casting to port. I would only buy them however if they were reasonably priced or already ported. No way anyone should buy them new when you can get a set of LE3s for the same price.

Careful now... the "you're taking me out of context" line is right around the corner. Watch out!
