I think it's too cool! Just remember, people call us nuts (sometimes we call ourselves nuts) for flying the Mopar flag.

I've seen a guy with a blown flattie in an FED run around here a couple times. IIRC, he did make it into the 9's.

I've actually done a lot of flatheads, and flowed a half dozen or maybe a couple of more and relieving the chamber is bad. Very bad. They also LOVE 50 degree seats.

Did it per neighbors request. The head/ piston combo needed less static compression to work with the blower. Definitely not an expert on these! My question to you as it was to him.... How in the ψξεβ do you flow test this??? You need everything in place, and i see no way to put it on a flow bench? What I did came out of some flat head god’s book.

Live update!

At the shop now, did the initial breakin, adjusting the valves.

Should have known better than to give a “fact” relying on my few remaining brain cells.

“Owner is hoping for 350hp.” Dino doesn’t think they will get this, lack of headers, questionable head work, etc...

Should have a video and some numbers soon!

Still a cool mill to be proud of.

I'm assuming that motor has adjustable lifters, correct?
I remember them days Them bad old days a long time ago
I also remember having and using 5/16 adjustable pushrod in a early Firepower Hemi to se the valves

The dyno guy had to do a bunch of fab work just to get that engine ready to go. I'm guessing the bill from the dyno shop is going to be substantial.

290 HP is my guess.

W/r/t the old school baloney-sliced ram stacks:
Whoever thought this out paid no attention to physics. Think of the air horn as a needle jet (Mikuni, Amal, Kei-Hin). As speed increases, air velocity across the top of the stack produces vacuum inside the air horn - the opposite of what you want. Might add some air if reversed with the open end forward.

280 first run. Running lean, timing light not working. Attempting to fix both.

If the timing light isn't self powered it won't work with a mag.

Agreed
But running a flat head is more of a style thing than a performance thing. Airflow with those stacks is not an issue reving your blown flat head in a parking lot

That’s not a bad start 👍.

Very much so. The project is more than that though. Brought the engine in as is was running horribly, turned out to just be very fouled plugs. But still couldn't get much power out of it, so Dino tore it down, and it had the wrong pistons, sitting way below deck. New pistons and steel main caps added, and now looking to see what it will do. Yes, going to be a hefty bill!

Here is the last dyno sheet of the day. This was after one rejetting step, (have to remove each carb to do the jets), and playing with timing by ear, as it looks like the magneto blew the timing light.

It still appears to be a bit lean, so he's going to go one more step on the jets, get a correct timing light, and see what it will do.

Notice the RPM, and still climbing! But Dino, the owner as well as myself, (even though my vote doesn't count), were scared even taking it that high, and decided not to go higher.

Not bad! Jets and maybe timing should be good for at least a few more HP.

Was very cool hanging out and watching this one get done though, just something different and unique.

Here is one of the pulls.

Here it is in the dyno room.

And while we're at it, here is my engine on the same dyno years ago.

And just for your viewing pleasure, !

That’s a great running little motor. Very cool! What’s it going in?

Forgot to ask, I'll see if I can find out.

Neat old machines, those flatheads. My first car was a '51 Custom 2-door with the V-8. Sweet old car......

Man am I'm glad you guys didn't hurt anyone or anything with that rocket car, talk about to much power

Yeah, that was hilarious! We previously tried it with one engine, didn't do much, so strapped 3 on there.

Boys will play!
