Deeply damaged camshaft bore#1

I have a 327 2 bolt main engine that has damage to the #1 camshaft bore caused by a spun cam bearing. The deepest diameter of the damaged camshaft bore is 2.1010Ē. I've took it to several engine shops in southern ca and they all said that the damage is to deep. Is there any shop out there that can fix this? Is it impossible to put a custom metal sleeve into the camshaft bores to be able to fit standard sized camshaft bearings, or just make custom oversized bearings?

I presume you are trying to save an original block. Talk to these guys. https://rpmengine.com/ They are a bit north of you i think.

Re: Deeply damaged camshaft bore#1

Is there some reason youíre trying to save this block?

May cost more to fix then picking up another block for a couple hundred bucks

Re: Deeply damaged camshaft bore#1

You can sleeve it but it won't be cheap. In older machinery sleeving is often the only answer. You only need to repair the bad bore, not resleeve the whole cam gallery. Many automotive machine shops can't do general machine work, they perform specialized procedures on specialized machines, many automotive machine shops would be at a loss to make you a bolt turn you an oil pump shaft. try to find a general machine shop and talk to the old pissed off looking guy in the back, he can fix your block.

Re: Deeply damaged camshaft bore#1

Now that is funny Jim...and oh so true. Makes me wonder if youíre the old guy. Anyway when that guy is found the biggest obstacle will be convincing him the job is serious. He likely has other old brainstorms laying around awaiting payment.

I just picked up my block from QMP racing and they told me that cam journal #1 is 0.080 big and cam journal #2 is 0.012 out of round. The only way to save the block would be to line bore all the cam journals and install a custom oversized camshaft. The block is for a 1967 camaro rs. It’s a 327ci 210 hp block

Re: Deeply damaged camshaft bore#1

The only thing of value is the date code. Doubt if you have a partial VIN and it can be restamped if need be. Check some of the larger recycling yards as they index their cores by not only size and year, but date code.

If you positively have to have that block it can be bored to BBC journal size and roller bearings pressed in place.

But it would be cheaper by far to find, and buy a compete used SBC 400 short block out of a seventies Impala or pick-up in your area and just stick on your heads after you bore them for steam holes.
