Match this 500hp/500lb-ft Combo?

Even those Speedmaster Magnum heads that I did in that one thread for my truck would allow 500 horsepower with a 4-inch arm under it peezy.

Okay...... let’s explore that option.
Buy a pair of castings without waiting for the Black Friday sale.......(currently $798/Pr at Jegs).
Do them up just like what’s on your truck engine....... finished, all new parts, ready to bolt on for a HR cam that’s suitable for 500hp.
What’s the bottom line?

Then.......how much more if you’re 1/2 way thru the job and the buyer calls and says...... he’s thinking he really wants more like at least 525hp?
