You know a flathead wont start up on the dyno when the distributor doesnt turn ????
I guess they need one of those little adapter buttons????

Found a cam button adapter ( from Speedway Motors) at lunch, they installed it and the engine starts and runs.
Now they are fighting a carb problem etc. May get a dyno sheet on this one this week....???
 
wish I could ask my Dad if has a dyno card for this run!!

This is the beauty of JWL's book. All of his modifications are backed up with an average of 3 Dino runs.
And Jim the intake should beread to ship this week, if you still want to use ir. Sorry about the delay.

Got some more bugs sorted out and it runs now on the dyno.
Still got a carb issue as it wont pull 3800 rpm for hp test . More as it happens ..

If it's stock (looks like it) the power drops like a sack of sh1t at about 3700-3800 looking at dyno sheets. In John's book the stock dyno tests end at 3750. It's when the cam checks out. Hp probably in the 70-80 hp range.
I know these figures don't agree with Ford's dyno figures. Ford had a very happy dyno, and used the numbers to sell engines.

I dont think they have seen 80hp as of yet. The dyno software is dialed in for 3800 i believe..
Still tuning the carb set up. Raised the float for some gain yesterday...
 
Ok just had lunch with my flathead buddy setting up the 1939 engine.

Should be the last run as there are other engines to do.

AND it only took four carbs, 4-5 power valves , two complete distributors, a set of H10 champions ( wet from power valve) , lifter adjustment ( one came loose and killed a cylinder ) fuel pressure regulator and a shortened ful pump drive rod..
The carbs were the worst problem, they started out with the "trunk" carb , in the trunk when we bought the car! I had two rebuilds on a engine at the shop ( local buiolder with chevy blood) and the owner bought a nos 94 off ebay. Between all these they took parts from three carb kits and the assortment making a final carb that ran the dyno with the sheet above. Pretty sad for sure as even the new carb didnt run out of the box!!!!!!!

As usual theres always much more to the story but we are at the very least smiling a little bit today after the run above. Cant imagine even trying this one in a car......:eek::eek::eek:
 
Bubba, you said it has a 4" crank in it, is the rest bone stock?
I'm not gonna get sucked in to the trap of comparing dyno A against dyno B on power numbers, but hp peaked at 2900rpm? Normally on a single carb flathead the peak is about 3500rpm. Like I said, not talking about the hp number, just the rpm the peak is.
Any idea what's going on here?
