Just picked up an LT4 swapped '86 C10

[Rusty Nail]

* looks at his truck again...looks at them Production Numbers...dang.

That's not very many.
Hold on!
One of 6494
Dang! Wow man that's pretty fancy.

Who told you posting pictures with the hood closed was OK?
Name the guy. I wanna know cuz that is NOT COOL.

 

[Rusty Nail]

I don't think you really got one.

 

[Turbo4whl]

@Rusty Nail Rusty you are tough! New guy joined yesterday, was on line for 11 minutes and hasn't been back yet. We may see that LT4, give the guy a break.

 

[RecklessWOT]

What is an LT4?

To sum it up- at the time a corvette engine.

 

[RecklessWOT]

I love the idea of an LT4, I really even just want to LT1 swap mine. I could personally do without the wheels and massive drop but to each his own, the engine swap alone is enough to make me look past the other stuff lol

 

[Rusty Nail]

Yeah yeah..it requires pics to operate - welcome to the internet and tell AlGore I said hi.

Just ask Snopes.com = it's FALSE.
Al Gore DID NOT invent the internet.

See how that works new guy?
I has picks.

The LT4 was the special high-performance version of the new-generation LT1. It featured a slightly more aggressive camshaft profile, 1.6:1 aluminum roller rocker arms, lighter hollow intake valves and liquid-sodium filled exhaust valves, larger fuel injectors, performance crankshaft, higher 10.8:1 compression ratio and high-flow intake manifold (painted red) with extra material above the port available to allow port matching to the raised port LT4 cylinder heads. The LT4 was conservatively underrated at 330 hp (246 kW) and 340 lb⋅ft (461 N⋅m). It was introduced in the 1996 model year, for the last year of the C4 Corvette, and came standard on all manual transmission (ZF 6-speed equipped) C4 Corvettes. The engine was passed down to 1997 SLP Camaros SS and SLP Firehawks with 6-speed manual transmissions.

The LT4 was available on the following vehicles:

• 1996 Chevrolet Corvette only when equipped with 6-speed manual transmission (includes all Grand Sports) (Production: 6,359)
• 1997 Chevrolet Camaro SLP/LT4 SS 6-speed (Production: 100 for the U.S., 6 for Canada. There were 2 prototypes)
• 1997 Pontiac Firebird SLP/LT4 Firehawk 6-speed (Production: 29)

All 135 production engines for the Firehawks and SSs were completely disassembled, balanced, blueprinted and honed with stress plates. One in 5 engines was tested on a Superflow engine dyno. Every car was tested on a chassis dyno and then performed a 6-mile (10 km) road test.

I automatically assumed he was talking about the new 640hp LT4 from the C7 Vette. Second highest hp motor GM has put in a production vehicle

ETA: The newest GM engines are considered “LT” instead of LS. Basically same platform but slight differences and LT generation engines are direct injection IIRC

Also… at $17K from Summit probably cheaper than what the original goes for

Thanks for all the kind words, folks. Spent the weekend working through some of the wonky wiring one of the POs did. All lights are functioning as they should now, next up is getting the horns squared away, figuring out why my HVAC fan & control aren't working correctly, and getting the A/C squared away.

 

[F51 LRS]

Couple quick pictures from the ad just for you @Rusty Nail . The interior is all redone, which is nice because now I don't have to do it. Though, I will probably swap the wheel for either a period correct wheel or something a little more hotrod-y.

It has, I believe a 3,000 stall converter in it, which I'll probably swap out for something closer to stock since I'll be using this daily & will be towing my track car.

Very nice. I had a 96 vette with the LT4 for seven years. Fun car to drive.
What gears in the rear end and what transmission is it hooked to?

I believe they're 3.08s, which are not ideal but I'm running a th350 so probably the best compromise currently. I may looking into an OD trans in the future (potentially 700r4) with some better gearing in the 3.40-70 range, but TBD on that.
