Why on Earth would you remove an engine superior in every objective way to replace it with an inferior engine to obtain the most clusterfuck disaster of an ignition system in the manufacturer's history?

the optispark is only a disaster if you are a retard and install a $69 non oem, or $500 msd optispark (also garbage).
if you have an oem vented optispark (with mitsubishi sensor) , it becomes completely reliable.
if you have a non vented 92-94, you install a vent (and again use an oem optispark with mitsubishi sensor) and it becomes reliable again.
c7 lt1 is superior, i wont argue.
But put a c4 lt1 in there (and sell the c7 lt1 for a net profit), and maybe you could get in a magazine
If you are wanting 'old skool vs. new', why not go all-in and go with a 1970-72 LT-1?
The "LT-1" has a warm place in many hot-rodders hearts, while the C4-era LT1, while a fine motor (despite the optispark debacle) is rather unlamented.
"LT-1 vs LT1" makes for a better story headline anyways if you are looking for an article to grab eyeballs.
great suggestion !
everyone talks about doing a resto-mod (putting modern engine into classic car) but what about the other way around ? (You get the lumpy idle, etc)
I guess given enough time, almost any idea, no matter how unlikely, becomes inevitable!
I had a '96 LT4 and I loved that old Vette. I didn't have problems with the improved opti-spark. Regardless, putting even a heavily modded C4 motor in a C7 does NOT strike me as the greatest of ideas, regardless of whether or not a magazine prints an article about it, or how much ahead (financially) you may come out on the swap.
Why would you do that to a C7???
With creative thinking like that, I suggest you stick to it and come up with something that would appeal to more people, as opposed to appealing to a tiny segment of the Corvette community, which at best is what I think this might appeal to (and I stress the word "might" since I doubt this would have much appeal at all.)

The 1970 lt1 engine was a beast and had RPM to spare. If you are thinking about destroying a C7, why not make it an actual "Hot Rod"? Build the 1970 engine with freshen up stuff and drop it in. By the way, don't sell the new LT1 until you finish your project, you may see that the new LT1 was faster anyhow. JMO
Why on earth would you consider replacing an aluminum block with 20 year older technology iron block? You might get a mention in a magazine, but it won't be for the reason you think.
If you have the talent and $ to do such a swap, I think you could think of a much better swap than that! Getting all the computers to work properly, with all the gauges and nanny's would be a herculean task onto itself.
I hope you are using a salvage title C7 or flood car as a starting point. Otherwise, you are going to take a C7 maybe worth $50K and transform it into a C7 worth $5k?

I can quickly think of a long list of reasons to do a resto-mod, and not one to do it the other way around.
While putting a C4 engine into a C7 might get you into a magazine, you would never recover the investment because it would be a white elephant of a car that nobody would want.
The magazine carrying that article might not be one you want to be in either.

It would be extremely difficult to maintain communications with the various chassis systems, PTM, e-diff etc. Same issue with even putting an LS in the 7. The system won't/don't talk to each other absent a whole lot of work, perhaps not even at all.
Would be even worse/harder with a C4 LT1 - it'd be a major obstacle to integrate the engine into all the other subsystems.
Unless you can both turn a wrench and design/program engine and chassis control computers, then good luck. And good luck even if you can.

Anyone ever remove Gen5 LT1 and install late C4 optispark LT1 ?
