Camshaft Tech: 1937 Olds straight 8 cam regrind

we go though the process of regrinding a 1937 Oldsmobile straight 8 camshaft

That's really cool. I feel most shops would say "it's junk". Thank you for your time.

[@powellmachineinc3179]

You bet!

[@dougobrien2840]

Love watching and learning what you do .Cheers from Australia

[@powellmachineinc3179]

Awesome, thank you!

I repaired a 36 buick that through a rod through the block. It had a roller tappet cam. I welded the block up and replaced one rod and piston. I plastiguaged the bearings and then pealed the shims off the caps to set the clearance. It ran great as a parade car. I was really supprised to see a roller cam in something that old but most new ideas are just rehashed from what the oldtimers did in the beginning of the last century. I am from the first half of the last century too.

[@powellmachineinc3179]

Yep, rollers have been around a very long time

[@strokermaverick]

Liked, watching the cam lobe, clean up!

[@powellmachineinc3179]

Definitely

[@jkdwayne]

Great content Daniel , you cant see Cam grinding just anywhere.

[@powellmachineinc3179]

I appreciate that!

[@wayneskelly4297]

Awesome video. Danny at Predator showed me how the masters worked to move the table. Unfortunately I never got back up to actually see a cam being ground though. Neat stuff! Thank you

[@powellmachineinc3179]

You're welcome!

[@skylinefever]

I love seeing people save auto parts on way or another.

[@powellmachineinc3179]

Absolutely 💯

I am new to the '37 Oldsmobile F37, but I was surprised looking at the head, it doesn't have any valves on it ! It's in my shop because it I was blowing coolant out of the tailpipe real quick. Owner wanted to do head gasket and a bottle so I did that, and it seems to have worked for now, but it will not. Last. He wanted to do a Chevy 350 short block if the head gasket sealant didn't work. Trying to talk him out of that and just getting the head and block resurfaced with a new gasket. It already runs like a sewing machine. The crazy pedal above the gas pedal to start the engine really threw me off. I've worked on a lot of old cars but this one is my favorite I swear

[@bobbyhackney988]

The next engine I build will have your parts in it. Great work buddy

[@powellmachineinc3179]

Can't wait!

[@thisisyourcaptainspeaking2259]

Very nice work, sir! Thanks for sharing.

[@powellmachineinc3179]

You bet

[@markwelliver2566]

cool stuff! love it!

[@powellmachineinc3179]

Thanks!

[@alanmize5627]

sorry I cant type i enjoyed watching but could not hear a word said usually your audio is very good thanks.

[@powellmachineinc3179]

Sorry about that, Andrew made some setting adjustments as we used the new Gopro, so we will have it corrected on the next 1

[@jimstewart8394]

awesome

When you regrind lifters, are they reground to a rounded crown or more to a point? I have just found your channel and am learning a lot. Needless to say, there's a lot to this cam business.

[@powellmachineinc3179]

It's a full radius on the lifter face

[@edsmachine93]

Nice work Daniel. Is the Olds straight 8 similar to the Buick or Pontiac? Does the block have cam bearings or run in the block like the old stovebolt 216's? Thanks for sharing.

[@powellmachineinc3179]

Actually, this is the first inline 8 I have done, so I can't 💯 speak to it but I would assume the buick and poncho is very similar, not sure on cam bearings either, but I will check, alot of old stuff didn't have bearings

[@mitchm275]

what are you using for lube/coolant on this cam grinder? i have cnc machines and i am wanting to get a non oil based coolant and not be concerned about rust, and or break the bank buying the coolant

[@powellmachineinc3179]

We use Castrol synthetic grinding coolant in all grinders and there machining coolant in all the cnc's

[@turdferguson4124]

That’s amazing work, Daniel. How much can you take off of a lobe before you need to worry about getting past the hardened layer and into softer metal that won’t have the right wear resistance?

[@powellmachineinc3179]

All iron cams are through hard, most induction hardened steel is about .200 deep, carbonized cores .060-.125 deep and tool steel is through hard.

[@timmer2896]

Ya , pretty cool , long enough to be continued ,,,, lol. Did a couple. Straight 8 pontiacs way back for boats

[@alanmize5627]

I enjoyed wathing but could not a word.

[@powellmachineinc3179]

I don't understand your comment, check your wording please

[@jeremyking5684]

Whats the cost to have sbc cam reground?

[@powellmachineinc3179]

150.00

[@Anthony-nw5zv]

Mushroom tappet cam and lifters????

[@powellmachineinc3179]

Yeah, alot of old stuff was that way

[@RANDOMNATION907]

If I sent you a 'cam blank' , can you regrind a hydraulic flat tappet cam into a hydraulic roller lifter cam?

[@powellmachineinc3179]

The "blank" is a cast iron finish ground flat tappet cam?

[@RANDOMNATION907]

@@powellmachineinc3179 Unfinished rough ground 'billet' for an AMC GenIII 360 cid V8.

[@powellmachineinc3179]

@miscellaneousone if it's roughed in as a flat tappet design there probably isn't enough nose radius to make a roller, is it steel?

[@BrokenPortriats]

no way - save a straight 8 cam? who does that?
