Mopar Muscle, December 2019. Making Slant Six Sense: Part 3.
They port and shave the head. The porting job looks great. Lot of time and money to bring compression 'up to' 8.2:1 (and ported with stock valves). Still, an interesting read.

This must be a continuance of an article they started and never finished, about a year ago. The above must be a misprint, as the stock compression is rated at 8.2:1.

Changing "to" to "from" would make more sense?

Compression was measured at 7.2:1 before any work was done.
You need to read the article.
Jus sayin.....

Manufacturing tolerances were pretty loose on Slants. You were lucky if you got one that had 8:1.

I thought it was well written, good pictures and good details of the work performed.

Perhaps I'm alone, but I get the impression that pre-planning was non-existent. They punt the entire field.

Got the issue a week or so ago, and wondered why I couldn't recall the first two installments of a 225 performance rebuild. So the first two installments were from a year ago? I just started getting the magazine, this makes the third issue received, Mrs wjajr purchased it and others from the grand kids school fund raiser. Interesting stuff, including Mark Worman's diatribe.

That is 40CFM more than my Jeffrey head. They may skip right over the 12's and go into 11's!!! :D :D :D
