David Vizard, Uncle Tony's garage, Unity motorsport. Mission impossible Dodge 302 Head porting

Surprised that nobody has not mentioned what happens to stock 1972 318 compression ratio when 360 heads gets bolted onto it.

7.5 cr is about where it comes in.

So what? I’ll take air flow and a properly sized port over compression any day, and I’m the biggest advocate of high compression pump ga engines I know of.

In theory you want both but in the real world sometimes you can’t get both.

Take the better cylinder head every time and you’ll make more power.
