hey everyone. quick question. i know about the freeze plugs and heads. but is a vin stamped on a boss block like a 289 hipo? looking at a car tomorrow and he says the car has a real 302 block in it. the pic he sent me is not the best but it looks like boss valve covers r on it.
If it has the screw in then you can be sure it is a boss or 427 engine. The size difference will tell you it is a boss 302. Vin stamp is on bottom of block but I am not certain that vin is visible with oil pan on. Heads have part numbers that you have to confirm also. There are reports of not all vins being stamped on engines but I doubt it is true b/c it was required by law. If it did happen, then it would be a rare occurance.

Very true. These are the head casting numbers. 1969 - C9ZE-6090-A or C 1970 - D0ZE-6090-A or B servicereplacement : D1ZE They are located under then valve covers though.

well after looking over the engine it looks like it has boss heads on it, but the engine looks to be just a regular 302. was hard to see because the engine is in a 65 mustang but it looks like the engine did not have screw in plugs. heads r D1ZE90AA
Which figures. It doesn't make much sense to put actual Boss 302 cylinder heads on a regular 302 block. Any set of 351 Cleveland 4V heads will be nearly identical. You need only add screw-in rocker studs and pushrod guides. (OK, the intake valves on the '69 Boss 302 heads were slightly larger. But that's still not a reason.)
Actual Boss 302 heads are very valuable to someone restoring a Boss 302. For anyone else, it's a waste of concours casting numbers.
I can't find any reference to that casting number. I'm thinking you weren't able to see it clearly. But I'm pretty sure it's a 351 Cleveland casting number.
