Mild Modifications / Re: Engine swap--are all 327s the same?
« on: May 11, 2014, 04:09:23 AM »
1967 and back 327s had a canister oil filter and a breather tube behind the intake manifold. In 1968 they went to a spin-on filter. '67-back 327s also had different cranks with different size bearings, so there is a small-journal and a large-journal 327, the '68 and '69 being the large-journal. Pre-68 327 cranks were forged, '68 and up were cast. In 1969 and some late '68s the heads were cast differently and the '69 heads had accessory bolt holes for the longer water pump. Hope this helps.
