Default Detailed 1969 427/390hp engine specs?

I am new to the forum and have a 1969 ISO Grifo 7L with the 427/390hp engine (LM suffix). For the engine rebuild I am looking for detailed part#/ tech specs for
- the original camshaft
- the 7029215 Quadrajet

I am also looking for pictures of the engines, since many details (fuel filter, air cleaner, crankcase ventilation parts, engine colors etc) are no longer correct on our 43-year-old ISO cars.

This is a (too) big request, but any partial answers will be much appreciated.

For PMs use juergenmwilms@googlemail.com.

Hi J,
2 books that may help you with pictures and info about your 427/390 are:
'Vette Vues Fact Book of the 68-72 StingRay' by M.F. Dobbins.
and
'1969 StingRay GuideBook' by Rick Bizzoco.
They are both available from various Corvette parts venders.
Good Luck!
Regards,
Alan
