Bolt kit NEEDED to rebuild 4 valve engines seemingly gone obsolete overnight!?

[Chayton]

this is crazy you guys! Im trying to rebuild this engine but cannot get the main cap bolt kit anywhere. I was able to purchase the same kit maybe a year ago for $60 no problem. Now its been wiped off of the face of the earth!!! part number M-6345-A46 is sold out everywhere. Is my only other option really to buy the over kill $270 arp kit!? If anyone has any solutions or a source please let me know this is delaying things for me badly and I'm starting to get in trouble over it lol.... why does this always happen to me :mad:

When I get to the dealership this morning I will see if I can locate a set for you.

[Fastbob]

Wow, you are correct as there is no Ford dealer in the country that has a set in stock. None on Ebay either. I'll let you know if I bump into a set.

You check MMR in Cali?

Machine Shop?

Try ARP.

The latest catalog.

Man..this is not good news for me. I did check ARP I believe they have it but it’s much more expensive. Running out of time so might have to go that route but if ford really doesn’t plan on producing these anymore it’s kind of a smack in the face to 4valve enthusiasts really.

Does anyone know if the side bolts are reusable or are those torque to yield as well?

I don't see how they can be tty since you can't torque them. They go on just past finger tight. I've always reused them regardless.

Just spend $400 on ARP bolts :(

You can buy main bolts in small qty packages i believe

Two questions: Chayton, the part number you listed is for a 3V modular and seems to have 6 extra bolts (10 studded inner mains, 10 outer mains, 10 side bolts, and 6 non-studded inner mains). Am I wrong about there being extra bolts, and did that kit actually work for 4Vs too?

After some research and consulting with my favorite east coast part number nerd, here's what I have for part numbers to do a Ford main bolt kit:
10 Ford XF3Z-6345-AA (https://www.tascaparts.com/oem-parts/ford-engine-crankshaft-main-bearing-cap-bolt-xf3z6345aa?c=Zz1lbmdpbmUmcz1oY XJkd2FyZS1mYXN0ZW5lcnMtYW5kLWZ pdHRpbmdzJmw9MyZuPUFzc2VtYmxpZ XMgUGFnZSZhPW1lcmN1cnkmbz1tYXJ hdWRlciZ5PTIwMDMmdD1iYXNlJmU9N C02bC12OC1nYXM%3D), side bolts

6 Ford 3L2Z-6345-AA (https://www.tascaparts.com/oem-parts/ford-engine-crankshaft-main-bearing-cap-stud-3l2z6345aa), studded M10 inner bolts

I could be wrong about part numbers or quantities. If you know better, please correct me.
