I need a set of stock block main cap cross bolts for my 426 Hemi restoration project. Is there a vendor that sells stock appearing bolts?
Thank you for any information

Did you try a Dodge dealer or Mopar after market? If not try Glendora Dodge(800-946-6727 or 626-335-0261 and ask for parts) in Glendora, CA for both scope twocents

The correct RSC head marking cross bolts are not currently reproduced (and no, not even by AMK). Larry Sheppard sometimes has good used originals.

You could put ARP cap bolts on the inside cause no body would see them, then the correct bolts on the outside.

I just need one main cap bolt so I thought i would find a grade 8 bolt and use it. I will call some Hemi engine builders on Monday to see if anyone has a good set of stock cross bolts. Thanks

If you plan on running this engine, put the correct bolt in. I'd say all grade 8 bolts on the market are made in china, do you really want that inside this engine?

I don't want this to turn into a p'ing contest but I just went on the Fastenal website and they had a number of Grade Eight bolts that are made in the USA.

No pissing. Just the last time I tried to get some grade 8 bolts from Fastenal for my balljoint to spindle all they could get were china bolts. So, some of their stuff is US, good.

I am looking for one main cap bolt for #5 main at rear of block. It may be the same bolt used on big block engines. The cross bots are two different size bolts. I need all six so i do not have a picture to post.
thank you

AMK sells stock type bolts with correct head markings. They might not make an exact reproduction of factory Hemi bolts but what they make will look correct to 95% of the people. Personally I just use ARP 12 point stainless bolts on my projects since I don't care if they look correct.

These are the correct cross bolts for a Hemi. The only bolts I've seen from AMK are marked TR (which are not correct).

I have run an aftermarket cross bolt in my Hemi that has seen 9000 RPM if that really matters with zero problems. They were made in North American and I made sure of that 25 years ago. The only real difference is what is cast into the head of the cross bolt. My next Hemi Build will likely have studs on the mains and other places. If no one can see any of the fastening hardware on the inside of the motor why not build the motor with the best parts. Ask Scott to take some measurements on the cross bolt length and the thread length and go buy some American made hardware. They will not cost much so even putting them on the shelf can not hurt.

Thank you, 73DAD! Finally some REAL information. Ignorant blanket statements like "all Grade 8 bolts are made in China" really p!$$ me off. It's like a knee-jerk reaction. It's automatic with no thought or knowledge to back it up. It also is a disservice to those American companies and workers who are making good products in the USA. How do you suppose they feel when they run across such an ignorant statement? All their hard work is for nothing?
The marks on a bolt head are not cast. They are formed when the bolt head is forged. Part of the marks are specific to the company that makes them.

Do a Google search for Bolt Head Markings and see many many pages of information.

Better to be pi*sed off, than p*ssed on, I made a true statement, I went to Fastenall to get grade 8 bolts for my lower ball joints, and everything in their catalog was china made, their catalog, not mine, and show me one box store that has US made stuff, that you would put in an engine, but if you would have read what I said, then you wouldn't be a Richard Cranium. I know there are US made bolts out there, but you have to look for them, you just can't find them easy, especially if you live in a small town.
