ignition timing problem

[filh]

I 've just finished my engine rebuild and I have some ignition timing problem .
I've fixed new Catcams camshafts (260°/256°) with adjustable cam gears .
Both IN and EX cams are well timed (110° both , from TDC).
The distributor is well set( two marks aligned).
Yellow connector is shunted .
At idle , timing advance is at -(minus)5° (5° below tdc).That engine needs 10° at idle ....
The adjustment is at max . With the engine reving at 4800rpm , I have 29° timing advance .
I found the engine very slow , below 5000rpm, but much better at high revs.
Any help welcome
