Does anyone know how much the block itself is good for. I wanna buy a stock block and build this myself. It's been something I've been wanting to do for years.

Pretend the internals, bearings and such are made of....hmm....i dont know, tungsten carbide.

How much power would it take to split the average block?

Thanks fellas.

Edit: Found the answer I was searching for.

and how much was it...

My understanding the stock block GT block is good for 440 at the crank. maybe 450

most 2v GT owners can get around 450 at the wheels... even a few get to 500... but it's not just the motor you should be concerned about.. it's also the axle and transmission... Running that much power, I wouldn't feel comfortable without a new tranny, and a 31spline.

it all depends on the tune

I wouldn't go past 450rwhp.

The block it self is actually very strong and can stand up to over 500hp easy, but the weak link is the rods and pistons and piston pins. Those are the limiting weakness that keeps folks around 400hp. Although I realy wouldnt call it weak at 400hp your almost doubling its egineered load that it was made to run on.

Did you guys just conveneintly ignore what he said there?

I'm special. The block is pretty strong, its the rods, crank and pistons like said before that are weak.

It's been said that some peolpe have gone up from 600 to 800 horsepower with a gnarly set of internals. Which is way more than I need.


And yes, I know what the stock rods can handle. Thanks VARrifleman and 03sonicgt for reading. You guys get a star!
