Good evening. Im looking for a good used crankshaft and a couple con rods for a 300 or 350 gas engine for a row crop that Im working on. I placed an ad but havent had any luck. Thanks
 
I have H parts but I am not sure if they interchange. If they do I will be happy to sell them for a reasonable price.

I think late Super H and newer engines in that series have rods that work. The lengths are the same, but the wrist pin is of a different size. Possibly the journal as well (Not sure on the crank)
Bates Equipment will be a good source (Indiana).

Two different rods were used. Rods with 5 digit number before letters on them and rods with 6 digit number before a letter with another number after the letter. What number cylinders do you prefer on the rods?
5 digit # rods are more plentiful.
Farmall serial # 25080 and up used the other light weight rods the same as a C175. Engine serial # 48049 up if its not for the original tractor. Standard crankshaft journals were the same size from real late H through 350 tractors.
 
The rods I have are the 5 digit casting number followed by two letters. I believe it was 43785DD? The rod i need should be marked for #4. The pistons have the larger 1.109 pin.

Thanks for the help
 
Have rods but no crankshaft. Have had transactions with Zackary Hoyt before and he is okay. If he has the rod or rods and you want them, get from him. If he doesn't have them I can send ones with whatever cylinder number you would like on it if wanted.
 
H crank will fit in the 300 block. order H bearings. H rods will work too, if your using the same pistons you have now with the big pin pistons, then the H rod will swap right out with the 300 rod. if your ordering a new sleeve n piston set, they will be small wrist pins so youd need the adapter bushing to se small pin piston in the H rods.
