What to do...

Was the cam degreed when installed? How did you arrive at the 7000 rpm shift point? My 408 had a 260/264 .050" .690"ish lift flat solid cam, well ported Edelbrocks with a port matched Victor, 10.8-1, 3260# with 4.10 gears. It liked being shifted at 6400, anything over 6600 or under 6400 it lost et.


IMO, You've been offered good advice on the converter and Victor intake. Your 60' is off close to .15 and I'm not sure a converter will get it all. A Victor may help with the soft bottom end.

No I didn't have a degree wheel when I put it together.
I incrementally increased shift points and ended at 7000 when I ran out of time..
11.75 @6000rpm 115mph 28 total timing
11.70 @6500rpm 116mph 30 total timing
11.64@6900ish 117.73mph just tapping the rev limiter with 32 total timing
11.57@7000 with limiter removed 117.78mph with 34 total timing
All runs within a couple of hours of each other and 7000+ DA, I figured the 32-34 is gonna be where my max timing is since the mph didn't change with the same shift points.
