Re: Starved modified flathead
Main Jets and PVs can be obtained from Hot Rod Company. 50 and 52 mains sounds like 94s and not 97s.

Note: You can get jets from guys on this board, or even Summit. BUT - you should go through the steps that Pete gave you first - and it should idle just fine if you do. If it doesn't idle fine (with the jets and PV you have), then there are other issues (as at idle, you're not really using the main jets nor the PV anyway). For example, if you have a big ole' vacuum leak someplace - that can easily cause this issue. |

Re: Starved modified flathead
Just in case I didn't see this mentioned , make sure the throttle shafts are .003 bushing to shaft clearance, I had this info a while back I can't pull it up from the search on here , the center carb is jetted different from the outer carbs an power valves are also different size, I 'll try and find this info in my files , this is something I would not delete, I have a very nice Edelbrock 4x2, I was trying to decide whether or not to keep it or sell it. I'll keep looking . I bought a bushing reamer to rebush my carbs and new longer throttle shafts.

Re: Starved modified flathead
I found the previous post , I can't get it to forward , it was on 11/26/17, under torque tool for Stromberg .97,.48 . It should help you out , it covers specs. for this set up . if you can pull it up on search.

Re: Starved modified flathead
I know, I don't know shiz from shine ola when it comes to this kinda stuff... but I would think engine vacuum would be a rare commodity at full open throttle or less, especially without chokes in some 97.
I only spend my weekends with one carb. |

Re: Starved modified flathead
dschwartz, I found the info. that was posted in 11/17 when I inquired about the 4x2 setup used on Walt Dupont's Engine, I didn't ask what cam or cubic inch this was for , so results may be different, .043 main jets in all 4, #67 power valves in the two MIDDLE carburetors and #69 power valves on the two end carburetors. Parallel reamed .003 throttle shaft clearance.

Re: Starved modified flathead
Unless you have the ability to do individual cylinder profiling, or carb wet flow testing, all the carbs should be set up the same. The one exception might be a log type manifold which would be a VERY poor performer below 3500+ RPM.

Re: Starved modified flathead
After you get it running the way you want, please keep us informed on the effectiveness of the A/C, cooling components and temperatures at idle, sitting in traffic and 'on the road"..
Really looks nice. Good luck. |

Re: Starved modified flathead
That is one sweet looking flathead! I’d love to hear it run! I wish I had the cajones to attempt a four carb set up for the street, but I’m too chicken! Still I’m thinking of attempting a 300+ cubic inch flathead project someday. Where did you get the 4-1/2” crank?

Re: Starved modified flathead
Walt Dupont's 1940 Ford Coupe with modifies 276 ci flathead has 4 Stromburg 97's on it and he drives it every fay. I had a ride in it and it ran quite well, even at low speeds. This surprised me, but if you put enough effort into a project, you can usually solve most problems
