Something different?
 

I was up in the Chicago area last week, and many of the suburbs there have a "Main Street Car show" every Friday night, where they block off downtown streets and you can park your special interest vehicle. I went to the one in Wheaton.

There was an "A" coupe of some flavor, a hot rod, with an 8BA flatty but with heads I had never seen before. Spark plug spacing was very different, for starters. I asked the owner what the heads were, and it turns out he used to work at a CNC place, and just made his own three-piiece heads! The real shocker was, he said he cc'd the stock heads, then made the combustion chambers on his heads for 12:1 compression ratio!!

I did not get a chance to hear it run. I wouldn't have thought it was even possible to get that high with a flathead? I wonder how long the rods will last??

Note also the homemade injection system. He also CNC'd a custom torsion bar rear suspension that was very interesting.

Yep, here's an earlier blown version with 7.5:1 heads.
Would like to see what's under the covers.

That Latham supercharger is an interesting piece in it's own right.

There are some other crafty looking parts on that car.....some skills shown by the builder. 12 to 1 seems a bit of an exaggeration though.......but with his talent.........maybe?

Has he kept it "flathead" or has he gone the Ardun route of overhead valves. Can't tell with the photos.

Re: Something different?
 

It's a flathead

Hi,
Which town did you find this engine in? I am in that area and would love to dig it up. Thanks, Al K.
