59a Flat head
I am overhauling my flathead for my car. I am running a 3.75 stroke .080 over USA pistons. I decked and bored the engine myself with the help of a master machinist. i need more parts to complete the engine. I will post more pictures of the engine block soon. thank you

Re: 59a Flat head
thank you. The next priority is the valve train. I am getting new valves or nos Ford valves. i will post pictures of the valves, guides, lifters and clips as i get them. Here is an original valve marked "ford USA IS". this came from the engine originally which was rebuilt who knows when.

Re: 59a Flat head
You haven't said what the engine is, 59AB or 8BA style. The valves are 59AB style with split guides. If I was you I would install 8BA valve brain with straight stem valves and solid guides. Walt

Re: 59a Flat head
I see this is an older post, but I would put bronze guides and stainless valves in it, now is the time!!
I would also recommend a "moly" ring pack, preferably a "light" one. Some "Viton" stems seals wouldn't hurt either. Drilled the lifter bores?? Thanks, Gary in N.Y. P.S. Good luck! They run real nice when they're done correctly.

Re: 59a Flat head
Comment on the decking, a flathead block really should not be decked because of how thin the upper deck is. Hope it was a very thin cut! Looks good, I love doing almost all of the work myself.

By stem seals are you talking about the ones that slip on and are retained with a spring or the larger ones that go around the guide like stock? Thanks, Tim |

Re: 59a Flat head
i was looking at a metric set of rings. The Hastings brand is still USA made, very high quality i believe.

Re: 59a Flat head
Why "metric" rings?

The "metric" ring packs normally consist of a 1.5mm top, a 1.5mm second, and 3.0mm oil ring. This is the combo Ross supplies with theirs, we also use a 4.00mm oil ring occasionally on certain builds. The lightweight ring pack is worth a bunch of HP, but the block needs the correct ring finish. We also "block-plate" finish hone all the blocks we service, even the Flatheads (also in photo). Thanks, Gary in N.Y. P.S. Here's the bronze-lined guides, the "Viton" seals, and the block-plate for honing! We use the same plate as a fixture to "pin" the heads/gaskets to the block, like the SBC's. This procedure works really well and is all done by machine, not by hand. We are able to "pin" a block/heads today and pin new heads if necessary at a later time with no "fit" problem!

Re: 59a Flat head
If you are looking for original Ford NOS parts, Jim at SFP in Rosemead CA has about 7,000 NOS 8Ba Ford guides. Fred at SSO has NOS Ford bearsing, cam gears and gaskets among other things. I also got some NOS engine parts from Ron at Dennis Carpenter, and Tom at Then & Now in Weymouth MA. No need to put foreign parts in your flathead when there is still original NOS Ford parts available.

Re: 59a Flat head
Gary; a buddy of mine uses metric rings on his four groove pistons with no issues. I will verify if the finish needs to be addressed with the rings i use.
Those bronze guides look like they would work but would the umbrella seals keep the oil from getting to the valve stems and cause an issue? I agree with you gary a hone plate is the best way to go.

Re: 59a Flat head
Tim, you are correct i need to recondition the connecting rods as well. i will look at the french stuff since you mentioned it. Keep in mind If i race scta i need to use domestic parts. I was thinking of grinding off some of the casting flaws and roughness. I ground some of the roughness off the crank counter weights. it took a little work and needs more to get more smooth. the logic behind this is, the result would be a quicker throttle response, high revs, and a more balanced engine because the oil and air will slide off the counter weights when the crank spins through the air. I am testing out this theory. If i gain a few more horse power over standard i will be happy.

Re: 59a Flat head
Here is Mike's porting guide. I'll try to find the one on rods and cranks.

Re: 59a Flat head
I went with the French rods on my last 8BA build. I got them from Vern Tardel, they were cheaper( even with shipping to Alaska) than getting my original rods reconditioned.

Re: 59a Flat head
Ronnie, the shoulder dimension is slightly different, this needs to be verified.

The piston grooves must be metric size in width to accommodate metric rings.What pistons is he running that are 4 groove metric grooves?? What is the shoulder dimension you refer to. Rings have a thickness reference,a bore size reference,and a radial wall thickness. R |

These next two images demonstrate the amount of material that can be safely removed, especially in the rod-journal area where it has the least effect on overall crank balance; those huge counterweights look like tempting targets for losing a lot of weight right away, but they're essential to the inherent goodness in the Ford flathead V-8 crankshaft. First, without any carving . . . . . . and with about 2/3 of the carving work done. This is the other side of the journal in the previous picture but it gives a sense of how much material can be removed without jeopardizing the strength of the crankshaft. The center counterweights have just begun to be carved. This 4-inch Mercury crankshaft illustrates the amount of material that can be removed from the counterweights that straddle the center main bearing. I'll look around in my photo files for additional images and see if I can find any that will add to the experience of carving flathead crankshafts. Mike |

Re: 59a Flat head
Hi Mike, glad to see you're still taking nourishment. It's been awhile, Haven't done much porting lately, eyesight can't find the right spots anymore. You should ask Ray if he wants to sell the Bville motor, I understand it's still sitting there in the yard. Everything is going well here, Have a great day.
