I apologize if this question has already been asked. Will the LT1 motor that is being used in the new Corvettes swap directly in to the 4th Gen Camaros that used the LT1s or what exactly would be involved in that?

Thanks

I haven’t seen it asked before! Great question.

For clarity, I’m going to refer to the ‘93-97 engine as the LT1 and the ‘2014+ engine as the Gen5.

For the most part, this should be similar to doing an LS1 swap. LS1 swaps into LT1 F-bodies are nontrivial but well documented. Compared to the LS1, the Gen5 has different computer and fueling requirements, and there are probably a few more things that will end up being relevant.

I haven’t heard of anyone doing this exact swap before, so you might find yourself blazing the trail a bit, which will require significant skill, perseverance, and/or cash from your end.

For LS swaps, it is widely accepted that it’s cheaper and easier to go out and buy an LS1 car than it is to swap one into an LT1 car. It would certainly be easier to swap a Gen5 engine into an LS1 car than into an LT1 car. You’ll get more money selling the leftover LS1 engine than you would selling an LT1, too.

If you end up trying it, please let us know!

Hey thanks for the reply! I'll probably be going with the "or cash" choice. I am just kind of exploring my options at this point and didn't know if that would be easier than some of the alternatives.

The new Lt1 doesn't share anything with your current engine and will not bevavdrop-in replacement. I think it shares block architecture with the LS series engines so the place to start is with a LS crossmember. Then get ready to spend money. Lots of money...

What is the objective of this swap? Are you thinking it’s an easy way to achieve 460 flywheel HP? A lot easier and less expensive to do that with your current LT1 engine.

My objective is to have a streetable car with a good amount of power. My last "fast" car was a 2009 Cadillac CTS-V which I traded for a pickup and have been missing ever since. I just want that throw you back in the seat feeling again. This wont be a drag strip car but I'd like it to be quicker than the majority of other sports cars I will run into on the street.

And you can achieve that with your current engine.

In addition to the newer LT1 engine, you will need a controller (sold by GM Perf Parts) to run the engine. Fuel system will need an upgrade, trans may not bolt up, or require a new bell housing. If you have a 4L60E trans, you will need a controller for that. While the newer LT1 will "fit", there's the issue of the oil pan clearance. The newer LT1 comes in two versions - dry sump and wet sump. Where do you get a accessory drive kit that bolts your existing accessories to the newer LT1?

"Fit" is not the only issue that needs to be addressed.

So is there anywhere that makes drop in performance LT1 engines, or are there any reputable shops in the Midwest what will do the work on the engine I have?

I can't speak for everyone, but why not take the engine that you have, and build it for what you want. The right choice is entirely up to what you want to do with the car and how much money you want to spend.

I suggest you start by asking yourself to commit to some sort of goal for the car. Drag, autocross, street rod... Then go from there on how to most efficiently meet that goal.

For a long block assembly, here's an example..... not crazy about Golen, HP estimates may be a bit overstated.... but it is one source. There are others:

I posted the link to Ellwein Engines above. Better source. You would have to contact Karl. Each engine is custom built, to achieve your goals. The link takes you to his short block assemblies. There is a link on that page to details of most of the 83 engines he has built. He can build you a long block, or a complete drop-in engine.

And, finding a local QUALITY engine shop, willing to take your engine, build the bottom end to the level required for your goals, and use your current heads/intake, ported by someone like Elliotts Port Works, plus a matching cam from Elliott, is probably the least expensive path, if you don't want to get involved with the build and assembly.

Excellent advise!

Many other members here are thinking of a similar swap.
