Anyone do an LT5 swap? I was just wondering because all I have been seeing here is LS1 and LT1 swaps but no LT5s. I think it would be hard because they are so huge(heads and intake). But is it realistically(sp) possible or has anyone done it? It addition, what is the difference between a zf 6-speed and a t-56?

I've seen a few online before and 1 in person two years back. An IROC with an LT5...just about the coolest thing I've ever seen

There's plenty of space for them in the 3rd gen's engine compartment (more so than with a typical Big block swap which are a dime a dozen) and the LT5 just looks killer !!

The most difficult part (I would think) is getting a custom set of headers built as there's very little clearance at the sides (by the shock towers) due to the LT5 being so wide.

If I had an extra $19,000 laying around, I'd pick up the LT5 in a heartbeat.

As far as trannies, I have noo idea the difference between the zf 6-speed and a t-56 Sorry.

 

Wow that is awesome. Nothing looks as sick as the LT5 intake. Yea i would assume the headers would be hard to fit but at least I know it's possible. Do you know if it fits under the stock hood? I didn't realize that they cost so much either. $19,000 is about $12,000 more than I expected, but I guess that is true considering how many we put in the Vette's and how many are no longer in them.

 

you can find them on ebay occasionally. I found a clean engine on there a while back for $5k, dont' know what it actually went for.

this topic has been beat to death over the years. Consensus - if you have the money, it can be done no problem.

 

theirs a salvage yard here in Sac, CA they say the always have one in stock and everytime I've been there they've had one they sale them for $10 or $12,000 (motor/tranny/wire harness)

would be a cool swap though

 

The ZF6 is a much beefier (and way more expensive) unit than the Borg Warner T56. Both the ZF6 and T56 have different max torque ratings based on what car they came out of since both saw duty behind many differnet engines in many differnt cars. C4 corvettes didn't have a trans crossmember, just an aluminum torque arm supporting the back of the trans. So the ZF6's found in C4's don't have provisions for a crossmember.

The torque arm mount is also completely different, it resembles the mounting surface found on the differentials of thirdgens. One more difference is the shifter location and style. It is set way back, biased toward the drivers side, and is a linkage style, not the conventional top loader of the T5 or T56.

One more thing to consider is servicability. Although the ZF6 is damn near bullet proof, if you do manage to break one, you are in big trouble. Parts are almost impossible to find, and if you do find them they are outragouslt expensive. Also, rebuilding one is almost impossible because you need an oven. The bearing races in the case and on the various shafts are such a tight fit that they need to be heated up to like 400 degrees Ferenheit for 30 minutes or so to remove them! Forget about it.

To make a long story short, I love ZF6's but they are not worth the hassle. Stick to a T56.

 

Couldn't you just use a press to drive out/install the races
off the shafts?

 

I don't know man, SLP's old T-Ram looks a tad more freaky if you ask me....

I'm with ya man, that LT5 looks flat mean. Those were overhead cam engines werent they? Probably had a wicked powerband.

Maybe, but the T-Ram did'nt come with a pair of DOHC heads

Click on LT5

Exxxpensive tho

 

$27K for a LT5 that's crazy!

For that price you could buy one of those 572 big blocks and have a custom exhaust system, a new tranny, and a new rear end!

And still have money left over!

 

I saw an episode of motor trend or car and driver and GM had a 92 25th Anniversary edition concept where they put the LT-5 in it. That was one Bad *** car.
