Check out my car and talk to me about 318/340 swap

I know all of that. All I did was point out that there is no compession difference between 675 318 heads and milled J heads. I did not change your quote and say your car was slow. Back at you.

It was meant to be funny, hence the big smiley face. I don't have a clue if your car is fast or slow, if you're happy with it that all that matters.

Don't take your self so seriously.
