A 445 with 10:1 will need a 270/224 lobe retarded to 110 ICL or it will be fussy on fuel and timing. I ran a 270H in one in my truck and it had a ton of torque even at 110, but ran better everywhere with a 282S equiv 112 LSA on 108. That was 4200 lbs, 3.50 gear with 33 inch tires
That Comp cam isn't a bad cam, its a 270H intake, 280H exhaust, but you'd have to rock it back unless somehow you were well below 10:1
The Howards cam is likely better on fuel tolerance, but is just too weird for a healthy 445. Low lift, not enough .050, miserable ramps, etc
FWIW - I run a 280/286 230/236 112 LSA on 106 custom grind in my 462 and it peaked at 5000 with a Victor EFI intake. Don't undercam it. Calculate compression, better describe the heads, but likely neither is optimal for off the shelf 445 parts,
