W2 408 Dyno results today !
Here is a sheet for a 416 with a SFT cam, mild rpm heads, SV intake, 1-7/8” headers.
I considered these to be good numbers for this build, and didn’t feel like there was an issue with how the power fell off after peak.
Your motor lost about 10hp 500rpm after peak.
This one loses about 18hp 500rpm after peak.
You can see the VE numbers are dropping off hard at the top end.
It’s used up the available area of the heads, and the valvetrain has started to give up.
The cam was 265/270-106...... easy on parts lobes.
