Going on the pump this weekend any on want to take a guess and HP and TQ
To summarize

1970 cc 4v heads
Scat 4” cast crank, 6” hbeams, SRP dished pistons 10.7:1
Crower hydraulic flat tappet 238 248 540 540 108

It’s going to be all painted ford blue with factory tin valve covers for the stealth look.

.200 133

After my guess I figured I’d be a little light, congrats on the nice combo 
The torque peak was at 3K with a 4V head?

That's pretty stout, considering it's mostly made up of stock parts, and a mild cam!
And people always say that 4V head Clevelands don't make no torque!....well, but then again, it's nearly 60 cubes larger!
