Late 80's swirl port heads 302/714's

I know you hate the "Heart Shape Chambers, But with a flat top piston, it gave you some compression without rebuilding the motor.
It also gave you quench that the open chamber will not without some kind of dome piston. aka rebuild again. or shave the **** out of a 360/340 head for compression...........and then you end up with a Heart Shaped combustion chamber any ways.....


The answer is really simple. In fact, it's what Chrysler wanted and the answer is easy to find.

If you are using a flat top piston and want the CR up where it should be, make the heads flat and equal. Then do the math and stick the piston out of the block. It's that simple.

There is zero sense is milling the hell out of a set of heads like that for compression. Stick the piston out of the hole. I'd have to look, but my memory says I'm out .045 on my current engine and I've done stuff at .055 out. Doesn't hurt a thing.

Convincing a moron who has never done Chrysler stuff to correct the CR this way is another story.

Rise above their ignorance and do it like Chrysler wanted. Stick the piston out of the hole. Works. Every time.
