Real basic 500hp SBC street engine

[KnightEngines]

Dyno'd this yesterday, was a bit of a surprise package, goal was a very drivable 450+hp on a tight budget.
I figured it'd make 470-480hp @ 6200rpm - a safe margin above requirements.

It's real simple:
4 bolt 010 block
Scat 383 kit with pro I beams & icon pistons.
Romac Street balancer.
Mellings pump, moroso pan.

DRP heads with a pro-port cnc program through them (aussie company, in Ballarat), 2.08/1.6 ferrea 5000 valves.
Flow 300/220 cfm, around 210cc.
Crane 96870 springs etc.
Budget stainless 1.6 rockers.

Team G intake (all I could get, choices are limited right now, I wanted a 300-25 strip dominator)
Quickfuel cq750 carb on a 1" tapered spacer.

Cam is an off the shelf crane 242/250 on 106 solid flat tappet.

11:1 compression.

Fired it up, bedded the cam & rings, put the inner valves springs in & had it dialled in in 5 pulls, used like 3 gal of fuel total.
Jetting ended up at 74 front, 83 rear with a 3.5 power valve.
33 deg timing.

506hp @ 6300rpm, 479lb @ 4700rpm.

What’s it going in?

1/4 mile potential?

Nice match up Man the torque=stump puller

HQ coupe, older guy has owned it since '83.
Manual trans, 3.55 diff - not a 1/4 mile car.
In a car set up for strip it'd be in the high 10's I'd think.

All I see is proof of the importance of quality cylinder heads. Nice job!
