Lsx454
Idle curiosity got me wondering, what would it take to drop in an LSX454 crate engine in a C5?
Related to that, is there a specific year I would want to start with? Specific options to take advantage? Theoretically, it would be a daily driver (< 10k miles per year) and drag race ~10-15 times per year.
I'm not as up to speed on the C5 as I should be, considering I've owned a '97 coupe & '01 Z06.

I think the very first thing you need to do to get one into a C5 is to switch the reluctor wheel, or install one if they don't come with one. You have to make the computer understand where the crankshaft is. Past that the rest of it should just be tuning but I am certainly no expert on this. I think that should be about all you need along with a ton of tuning skills. Once you get a base ve table to get the car to fire I think tuning shouldn't be a big deal from there. But all the C5 computers expect the low-res reluctor wheel so that's going to be a must. Unless you intend on changing all the electronics in the car and I seriously doubt that.

Lingenfelter has a widget to convert the 58x signal into a 24x signal so a Gen3 PCM can work with a Gen4 motor. I have no experience with it personally, but apparently it exists:

I suspect that an LSX 454 would use LS7-style exhaust ports, so you'd want LS7-style headers, but I'm not sure how big the differences are.
There could be differences between some Gen3 and Gen4 sensors, but LS7 swaps have been done in C5s so I'm sure an LSX454 could be done as well.
You might get more responses on LS1Tech.com, the folks over there seem more knowledgeable about this kind of stuff. It's owned by the same company as corvetteforum.com.

Thanks for the responses all. Looks like the pinch points are the reluctor, exhaust & sensors. I'll check out the sister forum.
One way to address the weight is to use the RHS block. And I'm seeing now that a shop is building a 527ci LS using it. :O
Now lets up the ante with HammerHead Racing Hemi heads and E85! :O :O
