[Gmecm] flathead ford files?

I recall speedway has an? individual port efi kit? ready on the shelf but they dont usually advertize it, prolly cost prohibitive for roll yer own crowd!

The initial chip set up is fairly easy.
Depending on which ecm is used.
You just pick the injectors or donor you wish to start with and calculate the initial BPW-base pulse width for the ecm to use for the calculations.
If using a later system then you input the injector flow and the cyl volume and the software calcs the BPW.
?
Personally I would start with a V8 bin and just set the BPW according to the new engine size and injector flow.
?
If running a stock 221 flat head it really wouldn't need much so a 2.8l V6?throttle body could be used on top.
CFM calculators are out there so ...

A 221 at 4000rpm is only going to need about 200-250cfm.
?
I have?a BPW calculator uploded here.

?
The 2.8l TBI flows about 235-250cfm with an inj flow rate of 33lb/hr
The 4.3/5.0/5.7 TBI is about 500cfm and the 4.3 inj is 45lb/hr
?
so if we use the BPW spreadsheet.
221CI with 2- 33lb/hr injectors for the 2.8 TBI = a BPW of about 165.
?
So if using something like the 88-91 GM truck 1227747 ECM and a 2.8l TBI you set the BPW to 165 in the bin parameters.
Then when you start to drive it you will make corrections to the VE1 fuel table to achieve the proper fueling.
For timing you could take the factory distr specs and build your own timing table to replace the stock GM one which really is pretty anemic for an older iron engine.
?
This is only the tip of the iceberg to get started tuning!!!!!!!!!!!!!!!!!!!!!!

Hey David thats impressive, me likee.? Im thinking? a little different though,? Im scheming? my own intake?, Ive been talking to a foundry and am a pattern maker,? 
?
side saddle digital midgets-port injection,? I wish i could be less cryptive? but.....
?propriatory? until reality.? 
? 
So how could a bin be built? for a 38-48? or later, the only small V8 as i said is the rover/buick olds 215? 3.5

tell Richard to check out the retro caddy batwing air cleaner? by obrian truckers-formerly bitchen products--a NICE cast aluminum downsized version with three different tops avalable!

I have done this! Got a 1944 4.0L Ford / Lincoln flathead running under TBI with 1227747 ECM.
?
The car hasn't been tuned or driven yet because the clutch and brake pedals and shifter aren't ready. The manifold is a real work of art.

Some pictures are here:

The only problem is, the engine has an awful cam in it and I don't think it will ever run smooth unless this is replaced.

Sincerely,
David

I don't know but it would be a favorite of mine as I have always loved the old "Flat Heads", first engines/cars I ever worked on.

?Hey with the nostalga craze, I wonder if anyone has done a old ford flathead? using a gm computer--there are electronic distributors on the shelf for them.? maybe something like a 3.5 rover hotwire system would be the closest, but yes im aware rover uses lucas stuff.
