'69 Swinger-340; 4 speed

well.. got the motor/trans pulled.

I'm a bit confused with the setup that was in place. The heads showed an 'X' so I was assuming 340 with x-heads.

But reading the vin on the block I read LH23D...... from there, didn't care.

I'm wondering about the heads, is this just a 273 with with 273 heads?
thanks.
