390GT using 428 CJ Exhaust Manifolds
By Walter - 03/15/2005 1:34:44 AM; IP 24.179.60.188
I currently own a 68 GT FB 390 C-6 Auto PS PB. Last week I pulled the motor to freshen up the motor as well as the engine compartment and attempt to remedy an annoying exhaust leak. The exhaust manifolds, suposedly, are 428 CJ and the bolt holes on aftermost port on the driver side don't appear to match up. All other bolt holes seem to mate up perfectly.

The numbers on the manifolds are as follows:

Drivers side; C80E9431B GL 11 188
(etched by hand "3009J101")
Passenger side; C80E8430D 1/12/6?
(etched by hand "300913")

Also, on the aftermost port of the passenger side manifold there is a small hole with a screw in it at the bottom. What is this for?

I am leaning toward replacing these with Ford Powertrain headers. They refer to a 14 bolt pattern for GT but I believe my heads only have a 8 bolt pattern. Tomorrow I will recover the numbers and confirm bolt pattern from the heads to ensure I have the proper heads.

A full ground up restoration was performed on this car 12 years ago but is in need a a bit of superficial TLC.

I plan on acquiring chrome waterpump, starter, alternator, waterneck etc prior to reinstalling. Any suggestions as to the best (i.e. most durable chrome products) source for these materials.

Any comments or suggestions would be greatly appreciated.
