GT heads casting mark

Postby guardrail22 » Mon Jun 12, 2017 4:13 pm

Trying to verify identity on a 70 GT.

Where is the C located on the head casting that identifies the correct cyl heads?

head code of a 1970 GT should be "E".

its got the big valve E-heads and the letter should be found on drivers side. you may remove the alternator brackets to gain access
