TT big block pros and cons lets here it!
 

Well guys it looks like the TT engine is going to happen. So lets here the pros and cons.

Pro: power and plenty of it

Con: weight, heat soak, cost, packaging.

Greg

If it is what you want and you are this excited about it... there are no cons.




Jeff-

Pros: It's what you want, aesthetics, power.

Cons: Weigh more than a sherman tank, nearly impossible to cool in some circumstances, handling, modulation for traction control, maintenance, reliability, packaging, cost.

I've done quite a few...there are never a lack of smiles!

The weight isn't the best option for a true corner carver. Large cube LSx would be more ideal if this is a concern. It'll still handle with the right springs and sway bar...just be a a few % heavier on the nose.

If you have e85 available, you can run without an air to air intercooler which will be your biggest concern to cool the car. Next option would be pump gas/water meth setup. Either will make much more power than the street can handle. If you feel an air to air is required, the air ducting and fans play a crucial role in cooling the car with a large restriction up front.

I have a 572" BBC w/ twin PT76GTS in my 55 Chevy. It'll run 150mph on 15lbs of boost (e85/watermeth) in the 1/4 mile. It's a beast at 4000+lbs but the 4L80e and extras really play a large part aswell. Scares the crap outta anyone that rides beside me!

Mario,

As a friend of mine used to say...

"Temporary inconvenience for permanent (in this case Perm-a-grin) improvement."


BTW-are you going to use an aluminum block?

Thanx Dennis ! I will bring this up to Steve.
No aluminum block Skip . Steve wants to use my 572 .:D

Well, I got to hear this twin turbo LSX engine run in Brian Thomson's Street legal 96 Impala. With over 2,000 on tap. I am not sure why people want a big block.

My buddy made 950rwhp with a stock LS3 block, $100 LS crankshaft, $600 compstar rods, and off the shelf Diamond pistons. He runs budget $1400 SDPC ported LS3 heads and stock LS3 intake. $400 cam, $500 morel lifters, stock rocker arms. He runs a GTS76 single turbo and $400 Treadstone intercooler. e85 fuel

Engine weight is around 425lbs without turbo.
You will save hundreds of pounds off the front end with LS power. His engine revs to 7800rpm when needed. 7K normally :D

He runs a $1100 Mcleod RXT twin disc clutch that has the pedal pressure of a Honda.

No need for TTBigBlock unless its a drag car. You can into plenty of trouble or out of it... running a turbo LS setup.

A stock 6.0 LS shortblock, stock ls3 heads/intake, medium size cam, single s480 turbo recently went 8.65@157mph in a Mustang running a TH400. Imagine what a built up one can do.

I'm hoping to run some 9's with my '69 Chevelle project and if not... I'll put on a bigger turbo.

Pros- it's not an LS

Cons- it's not an LS

It's def the package I'd go for given that budget. Sure the LS is lighter, smaller, better tech, and apparently made by god- but who cares. Build what you want. If you set the car up right, nothing will catch it from a roll anyway. Hard to argue your car handles better when a guy just put 10 bus lengths on you. lmao
