Baby Ruth abd the big engine.
 

And the story begins......You saw the little 258 engine in a previous postm The owner said the engine reved to hi and he was afraid he might loose the family jewels. as well as the boat, He sat right behinf the trans.
I suggester a bigger displacement and a different prop. So I put together a 284 with all the trimmings, It dynied out at 174 HP. But it couldn't beat the little engine for speed which was in the low 60s . So much for horsepower.

Re: Baby Ruth abd the big engine.
 

They look like Mike Davidson’s “Flatattack” heads from Australia

Re: Baby Ruth abd the big engine.
 

Their from Mike Davidson and you can get them from Reds. If they still have them. Even have the spark plugs in the right place,

Re: Baby Ruth abd the big engine.
 

Thank you Ron, and Merry Christmas!! I agree, those flatattack heads have the plugs in the ideal location. Also, very interested to hear the 'little' motor went faster than the 258. I've been spouting off on here and elsewhere, for so long, about how good the little 221's are; about their propensity to rev.

Re: Baby Ruth abd the big engine.
 

I suspect that the intake ports are the final "throttle" in the intake tract, being the limiting factor in airflow. Since the ports will only allow "X" CFM's to pass, it stands to reason that a 'big' engine can't make as much power at high RPM as a 'small' engine.

Re: Baby Ruth abd the big engine.
 

I think this debate will go on forever, but the intake and exhaust ports are what the engine breaths theu and the newer modern cylinder heads address this. I guess that's why the LS engines are more powerful than the original SBC engines. However, I think we'll be still learning about thes old flatties long after we're gone. I still have a few new ideas, might work, might not. It's the journey, not the destination.

Ol'Ron: Does the owner have any videos of the boat up on plane running. Very cool. A friend in town have a 6 cylinder Ford flathead boat motor with 3 carbs. They say it came out of a 21 ft hydro. Thanks for posting the pictures. Dave/Green Bay

Re: Baby Ruth abd the big engine.
 

No, I wish I did. There must be allot of pics some where as he raced it quite a bit around 20 years ago BVC (Before video cameras)

Re: Baby Ruth abd the big engine.
 

They can be made to flow as much as a stock SBC port and what with modern ultrasonic gauging systems, there is not much chance of going through into water or air.

Couldn't find the baby Ruth boat but did find a video on a supercharged flathead boat. https://youtu.be/Xpx7ntWPLXs

Re: Baby Ruth abd the big engine.
 

Thanks for the pics. Didn't have a camera at the time so there wern't allot of pics taken, Never thought I;d need them. Now My memory isn't so good. Dave was a master craftsman. The quality of his work was better that great. I was impressed by his restored Cord s as well. Wish I knew where those engines went.

Re: Baby Ruth abd the big engine.
 

Mart,,,thanks for enlarging the pics,,,very helpful !
That allows a lot more detail to be seen.

Re: Baby Ruth abd the big engine.
 

No problem Tommy, Anyone can do it. I showed how in my recent picture posting thread.

Re: Baby Ruth abd the big engine.
 

Pete, before I got so involved with Flatheads, I spent a great deal of time porting SBC , Olds and Y block heads. Now your telling me that you can make a flathead port flow as much. At present I plan on filling the water jacket above the port with Devcon liquid steel, si I can open up the entrance to the bowl. I then plan on welding a small plate to the guide to direct the flow awayfrom the rear of the bown. I also plan on using a 1.72 valve. The engine in the Hydro was similar except it didn't have the diflector plate. Which I think was your idea. also JWL made a set of guides which did a similar function. Now after all this the flow has to go out of the valve and make a 145 degre turn into the cylinder. I kinda think, this iz a bigger problem. I also spend allot of time modifying the cylinder heads to provide a better flow. The engines run pretty good, but not a hell of alot better than stock.
