The little cam normaily goes in 5 deg advanced. you want to cehck the timing before assuming it needs moving. You may have moved the big cam in the wrong direction.
If you did not degre it and jsut moved it to another keyway position.
This always gets you a inaccurate result.

Start degreeing your cams. you will go a lot faster.

12.4 @108 is fine for the little cam. the 60ft and et can be worked on.
launch. not enough gear if you want fast...
The high stall 4200 stall should produce the best ET with any cam.
The harder you leave, the better.

I bet that car weights more than you think.

A big solid will make more power and make the car faster but must rev to do that.
(gears) and the 4200 stall. Its going to have a rough idle and low manifold vacuum too.
Must have a free flowing exhaust to work. fuel system must keep up.
I don;t see you getting much further with 3.70 gears.

The heads need full porting to get the best from a camshaft.
the non platinum series 200cc IE is not near the Platinum series head.
need work to wake it up.
The 180cc IE head sucks....definatly needs serious work to get it going.
(modest out of the box flow for a 180cc head)

solid heavy casting head but needs work.
They were intended to be ported.

Solid lifter cam for your 406

Crane Saturday night special solid cam
Crane # 110921 or 110922 w lifters... makes a lot of street strip 406's go fast.
Degree it this time. 102 intake C/L ya it matters.
fix up the IE heads or swap to a good aluminum head (Profiler, Brodix IK200, AFR, Dart Pro 1)
use the 4200 stall and consider more gear.
The rpm manifold is fine.
A single plane manifold wants rpm,, will really like the gears, with that cam.
4.56's are not too much w a tall tire.
exhaust must be free flow or open. Get collector extensions.

Air-Lift rear air bags ("Drag Bags") work very well in those cars.
rear lower control arm relocation brackets help too.. launch traction.
