it's not a stock 360 it's a magnum, magnum head works really well, the 380hp create is a stock long block, with 230 cam 4bbl headers is a known low 12 even high 11 if setup right. Few that been dyno made over 400 hp, even with a mild 210 cam made 350-360 hp stock cam around 300 hp. An LA 360 is gonna need more cam to hit 300-360 hp and headed work to get over 400 hp. Why a lot suggests grabbing a running magnum add 4 bbl cam headers for cheap bang for the buck kind of our 4.8/5.3 LS just not as good :)

(I think he knows it’s not a LA 360….)
I don’t know the head flow values between the Magnum and Vortec’s. Have a link? I’d say there on par with each other in terms of what they followed.

True but 5.3 LS can get 500 hp with just cam and headers, most I’ve seen so far with magnum is 414 hp, magnum is more on par with older 350 vortec, still a great option for us low dollar mopar guys.

Yup

Even the 4.8 can get to 450 + hp, watch some Richard Holdener YouTube vids.

I’ll have to go back to those videos. I haven’t seen some and it’s been a while since I watched. Just the latest one with the Ford 302 & a series of heads he tested. Baby small cam as well.
