the heads are std. 67-70 cc out of a mid compact fairlane ,mustang comet etc. those are for sure 428cj exh. but out of a larger car the mid size cars used 14 bolt pattern thats why you see extra bolt holes. this still does;t tell you much. you can do the bore thing etc but the only way to know for sure is take the center freeze out on the right side of the block and look inside if there;s a 428 cast inside that;s what you got.my 66 gta has 14 bolt patternexh. and heads. |
