LT4 kits... Yes, or No!

[Dave M]

I was looking at the LT4 route not too long ago. I still am planning too once I get the funds. It's a very easy way to add about 100 hp. Don't forget this leads to PCM tuning, suspension work, rear end work, larger throttle body... it's a visious cycle!!

Try this link....... GM parts direct LT4 conversion Kit

Includes everything, even the gaskets at a great price.

Ok, I'll admit, the LT4 does outflow the LT1 heads when the same ported hits them. Up Top. The rest of the numbers are comparable.

My personal philosophy is that for the price of the LT4 kit, you could instead pick up some AFR's and really go the big route. The LT1 head (as well as the LT4) makes a great starting point when ported. But for the money, I'd rather go with a little more expense up front.

Personally, the LT1 and LT4 heads are so close in comparison that I just don't feel it's worth the time. Granted everyone plans for the future, and once you do the heads, there's always more that can be done, but really?? How many people actually pull and have their heads worked on multiple times for touch up inbetween setups. Only the really hard core guys, the "competitive" guys if you see what I'm saying. Most people want it done once and back to running. If you can't afford to port the LT4 heads, then don't get them and have yours done. Heck, even pick up a set of LT1 castings on Ebay or a board for $200-250 and don't waste any downtime on the car.

I'm standing firm in the fact that you can have a much more powerful car for very close to the same cost as that LT4 conversion.

I guess we'll call it personal preference then?

You are absolutely right and I completely agree.

If money is an issue, and you want to make alot of power than go with the ported LT1 casting.

If money is NOT an issue, and you want to make more power, then go with the ported LT4 casting.

Simple.
