What is the largest engine that can fit in the SL-C?

[Coleman Bee]

*Without major modification. Also, are there any examples of customers doing a supercharged AND dual carburetors on top of all that?

Even if they remove/cut the rear window...is this something that is feasible, or does everyone have to go fuel injected & low profile corvette style intakes...

 

[Scott]

My supercharged LS7 fits under the rear window without any issues. It's a Harrop which I think is taller than low profile corvette style intakes. Note that if you use a Daily dry sump and the right transaxle, you can drop the engine several inches which, in addition to lowering the CG, will provide additional room above the engine compartment. My engine is at the stock height because I fabricated a 180-degree cross over exhaust that crosses under the pan.

Coleman,

Here are links to various supercharged builds. Many different engines and superchargers. I’m doing an Gen V LT4 build and it took a significant amount of work to fit it in the chassis. Some of the work could have been avoided if I had more experience but that is the way these projects go.

Joel’s SL-C Build Thread

Hi everyone, I figure I’d get started and create my build thread. I ordered an SLC 8 weeks ago so delivery date is something like 8 to 16 weeks out This will be my first component/kit car although at 19 years old I semi-restored a 68 Corvette. Did some body work, hand made the entire interior...

S2's Build Thread

Yeah, the other Scott stole my build thread name so I had to come up with something else. I thought about GreatScott, or TheRealScott and even ScottWhoLikesTheSlcBody, but I settled on S2 My car was delivered last week... about as good as Xmas morning when I got a Six Million Dollar Man action...

LSA SLC Build Log

So It's time to get started ! I have been working on the car for a few months but have just now got the courage to try and start a log ! This is how I received the car from RCR. The LSA was fit in the car along with the required frame mods to make it fit.

Rogers SLC Build Thread

The day arrived. By new baby blue SLC. Probably the last of the rollers before Superlite switched to shipping in a crate. I have yet to unpack it as Christmas shopping and holiday family time. I'll post pics and ask questions as I progress. Thank you Fran and company for a great product.

SLC 001 Build

First week with the car - I spent last week taking a parts inventory, cleaning the car, getting the rear wheels pointing in the same general direction, measuring and re-measuring wheel offsets and brake caliper clearances. ''Measure 50 times - cut wheels once''. Now that I have something to...

Dont forget Stehpans build log. That Murcury Marine LS7 variant is large.

Stephan's SLC Build Log

Stephan's SLC Build Threat Hello fellow current and future SLC owners. My name is Stephan and I just received the majority of my 2017 white SLC on Sunday, February 25th. Graziano, flywheel and Infinity box still to come due to backorders... I am in the Yardley, PA area wanted to introduce...

Thanks Roger for remembering. The engine came with a shoe horn .

 

[Dan]

Aside from Stephans build and the BMW V10 build, has anyone else built a twin cam v8? Stephan, as noted above found it to be a challenge to fit that engine.

Dan there was at least one Coyote SLC build that I know of and a Maserati V8 as well. Both overhead cam although not sure if they are twin cam.

 

[Stephan E.]

I remembered a few others with DOHC.

Audi V8
Heffner Lambo V10 Twin Turbo
Mercedes V12
Ferrari V12
Toyota J2Z Inline 6
Lexus V8
Ford V8 Coyote

Checking back in on this thread...Im pulling a couple of thousands together at a time over here, and seeing options show up online for larger engines than the LS7 / 427ci variants.

Anyone see a glaring red flag going as high as say, a 496ci? Myself and my family has a little experience with engines this large because of our history in drag boat racing in the 90's, so I am tempted to do a large displacement, naturally aspirated dual carb setup. it will likely be too tall for the body of the SL-C though.

This is also coming from the fact that I dont have a lot a actual background working with fuel injection at all. I have a conceptual understanding of how they work, and how they can be upsized and boosted to match a performance motor setup, but it feels more foreign than your classic muscle car setup.

So anyway...any ideas what Fran would say about the largest Chevy engine size that the car can take? This of course includes the oil pan dimensions, not just the topside of the engine.

Hi Stephan, How did this thing feel when you needed the acceleration, at various RPMs? Did you find yourself favoring a certain part of the powerband, and if so what situations?

Right now I am building an aluminum block Donovan, which is a racing copy of a small-block Chevy (SBC). It will be 408 cubic inches displacement: a standard 4" bore +.030" oversize and a 4" stroke. It is possible to build a SBC up to 427 CID. The SBC is a relatively compact V8 that will probably fit but Fran should be able to advise you.

The Late Model team I was on had engines built by Tesar Engineering.
One of the engines was a 435” SBC that pulled 820hp on B110 and Methanol. Certainly was not inexpensive though…

They call it a "small block" but that is a completely new engine.

 

[Coleman Bee]

Thanks guys,

I'll stick with a 427. I will likely just build it myself and go with all forged internals, get it running naturally aspirated and then decide exactly how I want to finish it.

Hoping Superlite doesnt go out of business by then

“Hoping Superlite doesnt go out of business by then”

Um…what?

Ford or Chevy? BB or SB?

Remember you'll need a transaxle that can handle the torque.

The engine in the Dodge Challenger Demon 170 can be bought separately for nearly $30,000 as a whole unit, or $19,000 as a long block.

Yeah I backed off on the idea of going higher than a 427. 1000HP Graziano is the limiter for me.
