360 small block
I want to know what hp and tq i will be making my setup is holley 670 street avenger edelbrock airgap 268h cam summit headers 2.5 exhaust 4.10 rear end gears and heads milled .020 and a functional hood scoop

yes the cam is installed at 106 i milled the heads to true them and cr bump the compression is 9.0:1 casting# im pretty sure it isnt x or j heads. headers are 1 5/8 long tube

Nice build, should be fun motor.
I agree with estimate above.
Assuming stock valves and flow and properly matched valve springs to cam I got 322 HP / 365 Ft.LBS.
Keeping all items the same and switching to a non modified LA replacement RHS/EQ head with stock off the shelf mag valves and the numbers swelled to 361HP / 402 Ft. LBS.
Remember this is all theory for crank numbers: Tune, drive train loss, fan drag, pipe bends, etc will all change rwhp numbers.

EQ makes a Model 318 head that is drilled for LA manifolds and flows 20 cfm more than mags, is better casting and takes all stock mag valves. These are inexpensive heads. And make a ton of power. I run these. Ive run RHS. They both come from the same foundry in Australia.
You have a couple options:
Boneyard mag motor and do the long block swap. Gets you lighter rotating assembly and roller valve train.
Or EQ heads and keep what you have.
Once you have a decent head flow you can cam it to get your peaks dialed in.
You trying to cam it for a Ram 350?
