No one will mistake that for a 302. The pad is a different size,
the heads won't have the "humps" it will be obvious that it is a "new" engine.

It's your car, You can do whatever you want.
You need to be happy. Crate motors do come with warrenties.
But an era correct crate motor - no way.

Why not find a 1969 010 block (very comon), port your 202's use ARP's everywhere, HiPO pistons and rods, use rollers, and all HiPo internals.
But when you are done, you have a screemer all authentic "302"
Well it will really be a 383, but you don't have to admit.

With a crate motor it is not a Z/28 anymore.
The Z/28 was the 302 engine option.

I just really hate to see crate motors in authentic cars.
