Wow, that's an expensive 445 hp.

I feel like there was some bad choices on cam and head work in that deal. Maybe there is a reason they did not choose a different cam.......Idk....but talk about leaving it on the table.

And folks wonder why the FE gets a bad rap in the media.  We made more horsepower that that with a 302HO with completely stock shortblock and 5psi back 30 years ago.  Joe-JDC

I watched the video and it appears he's using a Performer 390 intake.  He makes a point that this is a very mild build and isn't supposed to be a power hero.  Maybe it will last forever like that?  It's always hard to judge someone else's work when you don't agree with or understand the premise.  He probably got exactly what he wanted.

Could be, but that supercharger is just making heat if it can't push through the intake and heads which is no benefit.

FWIW, with a 216 duration cam, with good heads on a 347, we did 370 naturally aspirated, put the belt on did 586 hp at 7.5 psi.  Was gaining every pull with RPM but we were afraid to go any higher with a stock iron block
