Where are you buying the "LT4 Conversion" package? GM no longer sells it because they have discontinued some of the parts, like the LT4 intake manifold.
Why would you buy the kit? For a lot less, you could have your stock LT1 heads ported, get a cam specifically matched to the heads, and make at least 50-75 more HP than the LT4 conversion.

Jeff, like Fred mentioned, the LT4 conversion package was discontinued. However you can still get the LT4 intake manifold and LT4 castings from a few places. Last time I talked to Combination Motorsports, they still had a line on both.
I agree that it would just be easier and better to port your own LT1 heads.
I asked you before......why are you so against using your own LT1 heads?

Just one example; you'll find dozens more online in For Sale sections on various forums.

Only problem, you're not reading the "fine print". He's not selling the LT4 intake with the $1500 package. Add about $950 to his "great price" for the real deal...about $2500.
Not so great anymore...
Because the intake is so expensive, the heads have dropped in value.Al 96 Ram Air T/A

And you don't have a very good knowledge of what things are worth. The fully ported fully assemble LT4 heads alone are worth the $1500.
BTW, trying to suggest that a price for a specific part is somehow the fair market value or the 'going rate' for that part based upon it's common price on ebay is not very smart. I 've seen pieces of grilled cheese toast that reportedly resemble Jesus go for $20,000. So what's your point??
I can get my hands on several LT4 intake manifolds for less than $300. In fact I just saw 2 of them a a small local swap meet. There are likely to be a bunch at the national swap meet at the Texas Motor Speedway this coming weekend.

Kevin...buddy...ease up. No flame intended Just making conversation.
I was just trying to support Fred's opinion (as well as mine) that because the LT4 package has been discontinued, the argument to do the LT4 conversion over porting LT1 castings no longer holds water...that's all.
Granted, if you look hard and long enough, you can find good deals out there. However, trust, for me at least, comes at a high price. Would I spend $1500 on used, ported LT4 heads that suffered damage requiring repair...maybe...maybe not. Now, if it was someone like Fred or Ken selling them...I'd buy them in a heartbeat. Why? Trust.

I've suggested to him all along to just get his LT1 heads ported. We shouldn't make him feel bad or naive in some way just because he has his heart set on the LT4 setup. If he really wants to go the LT4 route, then by all means, I will help him to find the LT4 parts.
