Cam Bearings Chevy Inline 6 250 292

[@steveshafer4023]

I always put the last cam bearing (usually the front) in backwards driving it into the block from the rear.... this way the cam bearing and tool remain in perfect alignment.... great tutorial!!

hi how are you? I came across your channel. I was doing a fast view of your videos. I Am from Argentina, where there are many Chevy inline six, I believe in Argentina is one of the places in the world where Chevy six inline was highly developed in performance, especially N/A engines. Congratulations on your channel, it's awesome that you share this type of videos. I Will Be looking for new videos regularly. Regards from Argentina!

I’ve been looking into building a 250 inline for my 84 caprice coupe I have been looking at sum videos from Argentina n they build sum nice boosted and N-A engines over there

[@telowe2000]

Argentina, definitely has it going on with the inline 6's.

Ok so how do you fit the cam in of it doesn’t fit after the new bearings are installed!!!

Love these engines. got a 250 in my 76 gmc stepside 4x4. not fast but sounds great and is the most reliable vehicle in my fleet with over 800,000 miles all oem parts. sadly shes worn and showing her use. been thinking of doing a 2006 4200 vortec inline 6 swap.Thank you for the vids.

I am so happy to watch these I look forward to get all my engine parts from 12bolt!

Thanks for the feedback!

Just found your channel. Very good content. I have a 250 chevy and a 300 ford setting aside waiting for a project.

[@jfair7050]

Hey Tom, I must be missing something.. If the middle 2 cam bearings are smaller on the early 292/250? blocks, how do you get the first big end of the camshaft through them 🤔 Or is it just the outside diameter of the inside bearings, which is smaller and all cam bearing surfaces are the same size (which is probably the answer and this is a stupid question).. One more question, I'm in Oz, where we have the little brothers of the Chev inline and I know some engine builders (in the past) used to half cover the cam bearing holes, to increase oiling pressure, to where it was needed more (main bearings etc) as cam bearings apparently don't need as much oil, as they are not under load. Are there no oiling weakness points on the Chev inline?

Many thanks for posting this video!

Glad you enjoyed it!

Thank you Tom for another great class lesson, I always enjoy learning something new about your process of keeping these great motors on the road. What engine stand are you using, it looks like a really nice unit? Thanks for all the work you do for the inline community.

[@VinnyMartello]

his customer service is dynamite. He actually called me one sunday and helped me solve a camshaft related issue.

[@billarroo1]

My question is, on the older block with the larger 1&4 cam bearings, that is outside diameter of the bearings. BUT is the inside diameter different or the same ? Also is there 2 different cams. with different journal sizes or does the same cam work on both older and newer blocks ? THANKS.

[@telowe2000]

All the cams have the same size OD on the 4 journals. It is just the OD of the bearing that can change.

[@VinnyMartello]

Another great video by old 12 Bolt Tom.

Glad you enjoyed it

Tom I have an 83 292. I have yet to pull it apart. I am going to put it in my k30 for tow duty. I want to know how your long rod/250 piston and small turbo will do for low rpm torque

[@myfastcars]

Tom Should the cam gear be able to touch the block if pressed rearward OR is there something that prevents it from moving rearward (controlling end play) so the face of the gear has clearance between the block and rear gear face?

[@wymple09]

Extremely informative

[@Moore20506]

Would like to know the difference between the inline 302 and the 292 . Bore an stroke blocks. Which one is best for racing

[@VinnyMartello]

The 302 is a GMC block and NOT a Chevy. Will be totally different. Really cool motors but less aftermarket support. I'm pretty sure the GMC 302 only had 4 main bearings while the 230/250/292 has 7 bearings. The crankshaft is much better supported and can handle more compression, RPM's, boost etc. If you want something interesting, get a GMC 302. But if you are more concerned about building a race motor, go 250 or 292.
