Guys here's the engine dyno video from the first Stroker LT1 engine ever fired. I know you have a lot of people on here selling package claiming flywheel hp without anything to back it up. That's exactly the reason why you don't see TSP selling hp packages after installing them one time. We extensively test combos before releasing them to the public. Starting Monday we will be shipping 630 flywheel hp heads cam packages! Now that we have several good h/c packages together we wanted to spend a little time on a few strokers.
Today we finally got around to putting the stroker camshaft into the 416 stroker & it responded very well.

This engine is:

416cid
4.065" Forged Pistons
6.125" Rods
4" Stroke
11.8:1 Compression
PRC Ported Cylinder Heads
Texas Speed Test Camshaft

Did you keep the displacement on demand? With that much power you could do burnouts in V4 mode haha

vegasredz062

what is the cost on this ? and can some one keep the stock cam, I really hate the rocking back and forth makes me car sick. I guess what i am asking is what would this package do with stock cam?

Jason 98 TA

You'd never do it with a stock cam. That being said a small cam would do fine. Probably make 640ish

vegasredz062

will this small cam have the rocking affect? how much would it make with heads and storker kit alone.I would prob ad a blower any ways once pistons and rods are forged.

Unreal

As you add displacement you can run a bigger and bigger cam without any bad effects. So you can run a bigger cam that would drive like a stock cam. I'm sure Jason can spec you a cam that doesn't rock/lope yet is correctly sized for a 416.

Great numbers.

Are those base line numbers on there? ~520 hp? I thought these motors are SAE certified at 450hp?

So we are realy looking at a ~150hp gain not 225?

Jason 98 TA

Yes that's the stock motor. The stock motor has dyno exhaust and open intake tube so it makes more power stock. The engine is also underrated.

Jason -

When do you expect to have RWHP numbers for the engine back in a car with full exhaust? It would be really nice to see with the stock headers and NPP what numbers just the stroker would make.

Also - are the internals strong enough to add a centrifugal blower later?

MitchAlsup

That is just sick! Good work.

Headers?

I need a new C7 and this motor. Almost 700fwhp with no adders and nothing exotic.

Jason 98 TA

Im working on the "lt7" 427 version right now! 700hp is definitely doable!

Jason 98 TA

The internals would easily take boost. Probably take some cam and compression out of it for boost, but the engine would easily make 1000.

JustinStrife

700hp N/A in a 427 C7 would... be... awesome..

How far are y'all from Ft Worth? I move there in January and I like having a local shop in which I'm not just a dollar sign. I've got two LSX conversions I need help on too.

Jason 98 TA

We are in Lubbock, but don't worry we have several approved installers in Dallas area. There's a lot of good people there!

VIN666

Oh man. Looks like this is going exactly as I was hoping
Makes the wait for the car even harder.
You guys were throwing 2.5k numbers for heads / cam around, which sounds awesome.
Any word on the rotating asm yet?

Late Model Racecraft

Great numbers guys!! These engines are so impressive.

The "rocking affect."
