Stroker 416cid LT1 Engine Dyno Graph Inside!!
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

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.

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.

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

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.
#9
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?

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

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

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?
