ultimate flathead
 

volume 50, #2 of "old cars" magazine, just out, contained an interesting article re: an engine put together many years ago and run in a '32 roadster. this was a 239, naturally aspirated with 3 97's and a few after market speed parts. dyno reading was 350 h.p. and rev'd regularly to 10,000 rpms, sometimes all the way to 12k. if you can acquire a copy of this issue, as i say, an interesting story and you can be the judge.

I read that article too, 10,000 on a flathead? Maybe that tach was reading wrong.

Somebody had their foot on the dyno beam scale.

Anyone selling popcorn? I'll looking forward to the responses about this one...

Re: ultimate flathead
 

Suspect the key words are in the first post, "this was a 239" :confused:

Re: ultimate flathead
 

With that kind of numbers, whether it was or wasn't a 239 is irrelevant.

Here's the article: https://www.oldcarsweekly.com/featur...ong-haul-deuce

"....Now 10,000 rpm might sound like a lot of fun, but it did present some problems."

Re: ultimate flathead
 

Getting that kind of RPM's is easy; just use a tachometer for a 4 cylinder engine.:D

Re: ultimate flathead
 

During this time, I once drag raced down Yale Boulevard in Nampa (this was a bout 1963). I tried a full-throttle power shift at 10,000 rpm and the result was a blown clutch, transmission, drive shaft, differential and a broken axle. Witnesses said the front end came off the ground a good 2 feet.

This is part where I stopped reading. I hope this author got an A in their creative writing class. Give me a break...

Re: ultimate flathead
 

Tub, I thought the same exact thing. Either wired wrong or it's a 4 cly. tach.

Maybe it's a case of the older I get the faster I was!:D

Re: ultimate flathead
 

Anyone catch the part about how fast he went after installing the 4.33 rear? The "facts" of this story are approaching science fiction levels.

Should have taken this beast to Bonneville. :D

Re: ultimate flathead
 

I liked this part:
The ’55 had an unbuilt 283-cid V-8 so I bought a motor adapter and installed the 283 in my ’32. What a disappointment that was. While I no longer had the heating problem, I had also lost a whole lot of power. It was OK, just not as thrilling as the full-race flathead.

Old Cars is usually a very interesting read, but this is ridiculous.

Tim Ayers: Your comment was fantastic. Liked the 2 feet off the ground.

Re: ultimate flathead
 

I guess the old theory about headers not helping performance on a flathead is true. This thing appears to have stock exhaust manifolds.
