Anyone know what parts interchange and what parts don't between the the ealy 287,316,336,347,370,389 and the later 63 to 81 326,389,400,350,301,421,428,455????
Do all intakes interchange how about distributors and can the later heads be fitted with the water ports at the front like the ealy heads?????
Are the bell housings differant and is 63 when everything changed???
