RE: 390GT using 428 CJ Exhaust Manifolds

The Jet,

Thanks. I've been out of the country for the last 17 years so it has been a bit of a challenge to dig out the old manuals and other publications. Last night I found an old book by Steve Christ that gave a decent account of decoding the numbers.

Regardless of weather its a numbers matching vehicle or not, its what I have and I have always loved the vehicle.

The basic questions still apply wrt quality billit alum or chrome products and where to locate them. As well as the issue wrt the exhaust manifolds or FPA headers. As is to be expected, I seem to get differing opinions from different sources as to what would be best. My biggest concern with the headers if ease of installation (i.e. can you REALLY slide the block with the headers into the eng campartment. Is there a leak issue like many of the old headers (remember my experience is working on these things 20 years ago). If the claims are true, I will probably go with the FPA headers and not deal with drilling and tapping the heasds.

I continue to appreciate the candid input from the Forum participants.
This thread, so far...
