292 rod bolts

[Ronfox69]

Hello all. Mabey this has been asked before. I have a 55 mercury 292 that needs rod bolts. Got a set of arp and they won't fit. The heads are too big. Called arp and they said that they know there is a problem but have no fix. Suggested I grind the heads of the bolts
Can't find another supplier of bolts. Anyone else run into this? Ron Fox in

I would contact John Mummert (ford-y-block.com), preferably by phone. You can also try Ted Eaton (eatonblancing.com) or Tim McMaster. Ted and Tim are at Bonneville Speed Week; I'm not sure about John.

Thanks for the reply. I bought the bolts from Eaton. Didn't get a reply from him. Mummert email said grind the bolts. Will try the other guy

Can the rods be broached to provide enough clearance for the bolts? A good machine shop should have an answer.

ARP has two different rod bolts for Y-blocks. Did you order the right bolts for your rods? If your 55 292 has the original EBU rods, you should have ordered ARP 154-6005 bolts. All other Ford Y-block rods would use ARP 154-6004. If you go to ford-y-block.com, you can watch their video of their H-beam connecting rods. The lack of availability of correct replacement rod bolts is addressed in the video.

Yes, I have the 6005 bolts

Anyone know of another supplier of rod bolts? Thanks for all the replies. This seems like a great forum . Ron

If both Mummert and ARP said grind the bolts, do it. Eaton’s probably going to say the same thing. On my 340 build I ground the bolts and the rods slightly to clear the cam. Those weren’t Ford rods, one of Mummert’s stroker kits with an offset grind on a 312 crank.

Have you balanced everything yet, or are you going to?

[Ronfox69]

Not balancing. Long story. The short version very bad rear main seal leak. Found seal journal on crank was pitted badly. On my third crank trying to find a good one. Just trying to get it back together properly so I can drive the old girl

[55blacktie]

The Ford Y-block engines are internally balanced. If you are replacing components, I highly recommend having the reciprocating assembly balanced.

Thanks for the heads up

So ARP knew they were sending you parts with issues all along. I'd call them up and ask them to send me a return shipping label, and tell them you want a refund. If they refuse call your credit card co. (Always ask who you are talking to).

Horrible!

[Ronfox69]

Thought about that but can't find anyone else who makes the bolts
