Running Raptor 282 degree camshaft and approx 13:1 compression. Fully streetable.

What size engine was that and do you daily drive your vehicle.

2332cc, 51.5mm IDA with 44mm vents. It's fully streetable, but it's not my daily. Idles at 1'000rpm (could go lower, but not that easy to get it stable then with such large carbs). Running it up to 8'000rpm with 0.9mm deck height without any problems.

0.9mm that's almost 40thou. How much CC are you running in the head and what head are you running. I want to build a 2387cc engine for daily driven with at least 200 ft/lbs of torque at the wheels.

Was wondering if JPM had any cams that can do this.

Approx 40cc IIRC, plus approx 2cc valve-pockets in the pistons.
SCAT Wedgeport 44x37.5 with 15.1mm lift.

No idea on how much torque it's producing, but it was enough to take out my R/P while accelerating in second gear while jetting it.

Here's a vid with fan belt + restrictive muffler..
