[Tony C.]

Hi
I have 1966 427 390 with a build date of 2/14/1966 what would be the earliest and the latest dates I can use for the intake manifold #3866948.
Thanks Tony

latest would be 2/14/1966, although most would prefer 2/13 or earlier. I can't comment on the earliest although August'65 would be possible in theory.

I have #15521 built in '66 and it has an L36 engine with a Feb 23 build date and intake casting date of Feb 14.

Hope this helps.
