Comparison 340 / 289

Oh yeah....it seems like I also heard that those 4-barrel Cleveland heads are actually TOO big, and many people recommend the 2-barrel heads for the street. Ford.......just can't seem to get it right....:-D

I used to know a few old time Ford men that raced Fords very well back in the day. The Cleveland 4v head is not just to big for the street, but way to big for the street never mind for passenger car service. The 2v head is they head to use for most applications.

While the 4v Cleveland head has alot of good points for racing, it also has to be worked on in a very particular manor. (I was told this and not given insight, after all, who cares, it's not a MoPar.)
This head was more or less, in a monor of speaking, (SP! coming) Homologated for racing. (Told you about that SP!)

Super Stock days required these things.
