Silver Sport LGT-700?

I thought the LSX454 was targeted at drag racing. Not sure why you selected it aside from displacement....

Im lost on unwillingness to cut for a t56 but you cut for minitubs. Is it just because the paint work is done?

I ended up putting in a new floor in it since the previous owner had done a hack job on the original tunnel. I spent a small fortune on the bodywork and NOS panels so hate to cut it up.
I do not intend on this being a track car. I plan on doing power tours, drive it to events, and have a car that is enjoyable and comfortable to drive. With this in mind, what combination of motor/trans would be ideal? I am conscientious of return on investment so an LS motor is a must.

If built my car over again, the first change on the list would be slicing the tunnel and a 56mag. I was never happy with the tko. It's cheaper to do it right once.

My 1st choice of transmissions would be a T56 Magnum but it might require a tunnel mod. If a tunnel mod is not an option then the 2nd choice would be the LGT-700 5 speed. 3rd on the list would be a TKO 600. I don't think Tremec even makes the TKO 500 any more since it is not listed on their site.

Thanks for the opinion and ranking of the transmissions. I am going to look closer at the T56 and specifics on what it will take to install it. I read a Super Chevy article on installing it in a 2nd Gen Camaro and but it didn't go into details on the modification required.

Thanks of the input. How about the T56 Magnum with the LSX 454? Good combination? What engine are you running? What recommendation would you give for the motor?

When done correctly modifying the transmission tunnel will not be noticeable to 99.999% of potential buyers. It will however correct driveline vibrations that will sink the value of the car.

From a resale standpoint the T56 should havery more appeal than most any other manual transmission.

Unless you're planning stroking bigger, I'd stick with the alum block engines. Plus the LSX is dang expensive and weighs about 130# more

Why do people even consider the LSX it's a BOAT ANCHOR! The block is 260LBS there is nothing "pro touring" about a heavy cast iron lump in the engine compartment
